[SCSI] bnx2fc: No abort issued for REC when it times out
Browse files Browse the repository at this point in the history
ABTS was not issued for timed out REC, as REC completion handler exits out if
the IO completed. Check for timed out REC and issue ABTS before proceeding with
further processing in REC completion handler. Also, initialize rec_retry and
srr_retry before starting the IO.
