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 #. Signed-off-by: Sage Weil <sage@newdream.net>
