scsi: bnx2fc: Fix hung task messages when a cleanup response is not received during abort
If a cleanup task is not responded to while we are in bnx2fc_abts_cleanup, it
will hang the SCSI error handler since we use wait_for_completion instead of
wait_for_completion_timeout. So, use wait_for_completion_timeout so that we
don't hang the SCSI error handler thread forever.
Fixes the call trace:
