scsi: qla2xxx: Avoid double completion of abort command
qla2x00_tmf_sp_done() now deletes the timer that will run
qla2x00_tmf_iocb_timeout(), but doesn't check whether the timer already
expired. Check the return value from del_timer() to avoid calling
complete() a second time.
Fixes: 4440e46d5db7 ("[SCSI] qla2xxx: Add IOCB Abort command asynchronous ...")
Fixes: 1514839b3664 ("scsi: qla2xxx: Fix NULL pointer crash due to active ...")
