scsi: mpt3sas: Postprocessing of target and LUN reset
If driver has not received the interrupt for the aborted SCSI command
before processing the TM reply, driver polls all the reply descriptor pools
looking for the reply for the aborted SCSI command before marking TM as
FAILED. If it finds the reply, then it marks the TM as SUCCESS otherwise it
marks it FAILED.
scsih_tm_cmd_map_status() checks whether TM has aborted the timed out SCSI
command or not. If TM has aborted the IO, then it returns SUCCESS else it
returns FAILED.
