then Asuint32_t is going to be gargabe. This just fixes

This patch resets the cmd timer if cmds started before
the timedout command are making progress. The idea is
that the cmd probably timed out because we are trying
to exeucte too many commands. If it turns out that the
device the IO timedout on was bad or the cmd just got
screwed up but other IO/devs were ok then we will
will figure this out when the cmds ahead of the timed
out one complete ok.
This also fixes a bug where we were sort of detecting
this by setting the last_timeout and last_xfer to the
same value when the task was allocated. That caught
the case where we never got to send any IO for it. However,
if the problem had started right before we started the
new task, then we were forced to wait an extra cmd
timeout seconds to start the scsi eh.

If the netdev has not been setup when the host is, we will oops when
the iscsi layer calls into the driver and a it tries to reference the
netdev in hba->ndev.
This can happen if the iscsi driver is loaded before ifup is
done. This patch just adds a check, so we can gracefully fail the
operation.

After discussing this patch with LSI, I resubmitting with a recommended
40 second wait for the alternate ioc's initialization to complete.
--
Fusion FC chips are two function with some shared resources. During
initialization of one function its driver inhibits the ability of the
other function's driver to allocate message frames by clearing its
"active" flag. Should mid-layer error recovery be initiated for a
scsi command during this initialization (which can take up to 40 seconds)
error recovery will escalate to the level of host reset. This host
reset might fail (as the other function is resetting) resulting in
all connected targets being taken offline.
This patch holds off mid-layer error recovery for up to 40 seconds
to permit initialization of the other function to complete.

fix bug in adjust_hpsa_scsi_table which caused devices which have
changed size, etc. to do the wrong thing.
The problem was as follows:
The driver maintains its current idea of what devices are present
in the h->dev[] array. When it updates this array, it scans the
hardware, and produces a new list of devices, call it sd[], for
scsi devices.
Then, it compares each item in h->dev[] vs. sd[], and any items which
are not present sd it removes from h->dev[], and any items present
in sd[], but different, it modifies in h->dev[].
Then, it looks for items in sd[] which are not present in h->dev[],
and adds those items into h->dev[]. All the while, it keeps track
of what items were added and removed to/from h->dev[].
Finally, it updates the SCSI mid-layer by removing and adding
the same devices it removed and added to/from h->dev[]. (modified
devices count as a remove then add.)
originally, when a "changed" device was discovered, it was
removed then added to h->dev[]. The item was added to the *end*
of h->dev[]. And, the item was removed from sd[] as well
(nulled out). As it processed h->dev[], these newly added items
at the end of the list were encountered, and sd[] was searched,
but those items were nulled out. So they ended up getting removed
immediately after they were added.
The solution is to have a way to replace items in the h->dev[]
array instead of doing a remove + add. Then the "changed" items.
are not encountered a second time, and removed.

This is done by adding support for the so-called "performant mode"
(that's really what they called it). Smart Array controllers
have a mode which enables multiple command completions to be
delivered with a single interrupt, "performant" mode. We want to use
that mode, as some newer controllers will be requiring this mode.
