[SCSI] qla4xxx: Fix kernel panic during discovery logout.
Update the session and connection parameter before sending connection logged in event to iscsiadm because in some scenario logout may come in just after we send the logged in event to user, which free up session, connection and ddb, but DPC is still updating session and connect parameter which can lead to panic.
