Michael Chan 8ec3e70207 cnic: Fix parity error code conflict
The recently added parity error handling used an error code that was
already defined for a different error.  This could lead to bnx2x
firmware assert.  We need to fix this with new error codes that are
defined for parity error only.

Michael Chan 3238a9be4d cnic: Add FCoE parity error recovery
When bnx2x returns error on FCoE SPQ messages, generate an error
completion to bnx2fc immediately to speed up error recovery.  This
will eliminate length timeouts and spped up the reset of the device.

Michael Chan 23021c2105 cnic: Improve error recovery on bnx2x devices
When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages.  As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.

To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.

Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.

Michael Chan dcc7e3a6a2 cnic: Add timeout for ramrod replies.
If the bnx2x device has encountered parity errors, the chip will not DMA
any replies.  Using wait_event_timeout() will allow us to make forward
progress and let bnx2x reset the chip.
