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: [183373.131468] INFO: task scsi_eh_16:110146 blocked for more than 120 seconds. [183373.131469] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
