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
