Driver received a scsi completion after it posted the cleanup
request. This leads to a problem that one of the ref count wasn't
released leading to flush_active_ios to struck. The callback from
libfc never returned and other ports were not processed leading to
APD.
- The patch will decrease the refcnt as well try to complete if
something is waiting for completion.
