ceph: fix readpage from fscache
ceph_readpage() unlocks page prematurely prematurely in the case
that page is reading from fscache. Caller of readpage expects that
page is uptodate when it get unlocked. So page shoule get locked
by completion callback of fscache_read_or_alloc_pages()
Cc: stable@vger.kernel.org # 4.1+, needs backporting for < 4.7
