scsi: libsas: use flush_workqueue to process disco events synchronously Now we are processing sas event and discover event in different workqueues. It's safe to wait the discover event done in the sas event work. Use flush_workqueue() to insure the disco and revalidate events processed synchronously so that the whole discover and revalidate process will not be interrupted by other events.
