mbcache: don't reclaim used entries
[ Upstream commit 58318914186c157477b978b1739dfe2f1b9dc0fe ]
Do not reclaim entries that are currently used by somebody from a
shrinker. Firstly, these entries are likely useful. Secondly, we will
need to keep such entries to protect pending increment of xattr block
refcount.
