filestore: fix rollback safety check
There is a window in the old check between when current/commit_op_seq is
written and the snapshot is taken. If ceph-osd crashes, we'll be unable to
start because we'll believe current/ was in use without proper checkpoints.
Instead, make the snapped/not snapped state of current/ explicit.
Fixes: #2118
