Fix reference count leak for a case where snapshot's mount point is updated.
Such situation is not supported.

This problem was triggered by something like this:

	# zpool create tank da0
	# zfs snapshot tank@snap
	# cd /tank/.zfs/snapshot/snap  (this will mount the snapshot)
	# cd
	# mount -u nosuid /tank/.zfs/snapshot/snap  (refcount leak)
	# zpool export tank
	cannot export 'tank': pool is busy

MFC after:	1 week
