Solved a locking issue that resulted in driver crashes with the 43224 and 43225
chips. The problem has been reported on several fora. Root cause was two fold:
hardware was being manipulated by two unsynchronized threads, and a scan
operation could interfere with an ongoing dynamic calibration process. Fix was
to invoke a lock on wl_ops_config() operation and to set internal flags when a
scan operation is started and stopped.
Please add this to the staging-linus branch.

PCI PM suspend callback took down the interface and resume brought
it back up. In the mac80211 context this is done in subsequent calls.
Rework implementation so that suspend only stores config, and sets
PCI power state. The resume return to full power state (D0), restores
the config, and brings hardware back up. Full bringup is done by
subsequent mac80211 calls.

The driver assumed it would receive skb packets from MAC80211 which
are not cloned. To guard this assumption an assert was placed in
the transmit routine. As of kernel 2.6.37 it turns out MAC80211 does
pass skb packets that are cloned. The assert is also not needed as
it does not lead to a failure state in our driver when the packet is
cloned. Therefore the assert can safely be removed.

These macros use the equivalent of "#define WL_<type>(x) printk x"
which requires an extra level of parentheses.
Convert the macros to use the normal WL_<type>(fmt, args...) style
and remove the extra parentheses from the uses.
Add format argument verification using no_printk as appropriate.
Couple of spelling typo fixes in the formats and argument alignment
at the same time. Also coalesced long formats.
