mm: change vmf_anon_prepare() to __vmf_anon_prepare()
Some callers of vmf_anon_prepare() may not want us to release the per-VMA
lock ourselves. Rename vmf_anon_prepare() to __vmf_anon_prepare() and let
the callers drop the lock when desired.
Also, make vmf_anon_prepare() a wrapper that releases the per-VMA lock
itself for any callers that don't care.
This is in preparation to fix this bug reported by syzbot:
