switch mnt_hash to hlist
commit 38129a13e6e71f666e0468e99fdd932a687b4d7e upstream.
fixes RCU bug - walking through hlist is safe in face of element moves,
since it's self-terminating. Cyclic lists are not - if we end up jumping
to another hash chain, we'll loop infinitely without ever hitting the
original list head.
[fix for dumb braino folded]
