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
