mds: don't cap log when there are replicated objects
replicas may dirty scatter locks

Fixes: http://tracker.ceph.com/issues/36350
Signed-off-by: "Yan, Zheng" <zyan@redhat.com>
(cherry picked from commit 6c1d4c6)
Signed-off-by: Jonathan Brielmaier <jbrielmaier@suse.de>

Conflicts:
	src/mds/MDCache.cc: adapt to code around
mds: use MDlog::trim_all() to trim log when deactivating mds
The problem of MDLog::trim(0) is that it expires current segment.
New log events (scatter nudge) may get added to current segment
when MDLog::trim(0) expires current segement.
