scsi: bnx2fc: Process the RQE with CQE in interrupt context
Filesystem goes to read-only after continuous error injection because RQE
was handled in deferred context, leading to mismatch between CQE and RQE.
Specifically, this patch makes the following changes:
- Process the RQE with CQE in interrupt context, before putting it into
the work queue.
- Producer and consumer indices are also updated in the interrupt context
to guarantee the the order of processing.
[mkp: fixed bad indentation]
