scsi: fnic: Avoid false out-of-order detection for aborted command
If SCSI-ML has already issued abort on a command i.e FNIC_IOREQ_ABTS_PENDING is set and we get a IO completion, avoid this being flagged as out-of-order completion by setting the FNIC_IO_DONE flag in fnic_fcpio_icmnd_cmpl_handler Signed-off-by: Satish Kharat <satishkh@cisco.com> Signed-off-by: Sesidhar Baddela <sebaddel@cisco.com> Signed-off-by: Martin K.
