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.

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.
