ceph: fix readpage from fscache
commit dd2bc473482eedc60c29cf00ad12568ce40ce511 upstream.
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()
