[SCSI] qla4xxx: Fix cmd check in qla4xxx_cmd_wait

If the command has timedout then the block layer has called
blk_mark_rq_complete. If qla4xxx_cmd_wait is then called
from qla4xxx_eh_host_reset, we will always fail, because if
the driver calls scsi_done then the the block layer will fail
at blk_complete_request's blk_mark_rq_complete call instead of
calling the normal completion path including the function,
blk_queue_end_tag, which releases the tag.
