s3: Fix a deadlock between smbd and ctdbd

Do the notification after we released the share mode lock. Inside notify_fname
we take out another tdb lock. With ctdb also accessing our databases, this can
lead to deadlocks. Putting this notify after the TALLOC_FREE(lck) above we
avoid locking two records simultaneously. Notifies are async and informational
only, so calling the notify_fname without holding the share mode lock should
not do any harm.
