Log Message:
lagg(4): Remove unnecessary LAGG_LOCK holding while lagg_proto_detach()
to avoid deadlock in workqueue_wait due to LAGG_LOCK holding

lagg_proto_detach dose not need to hold LAGG_LOCK because only one
context can access to a detaching protocol after sc->sc_var is updated.
But it was held without any reason. And it had caused a deadlock by
holding LAGG_LOCK in caller of workqueue_wait
and waiting for the lock in worker.
