mds: include nfiles/nsubdirs of directory inode in MClientCaps

Directory inode's dirstat gets updated by request reply, but not by
cap message. This causes problem for following case.

1. MDS modifies a directory
2. MDS issues CEPH_CAP_ANY_SHARED to client
3. The client satifies stat(2) by its cached metadata.
