Subject: ceph: correctly set 'follows' in flushsnap messages

The 'follows' should match the seq for the snap context for the given snap
cap, which is the context under which we have been dirtying and writing
data and metadata.  The snapshot that _contains_ those updates thus
_follows_ that context's seq #.
