GFS2: Move "entries" into "proper" inode
This moves the directory entry count into the proper inode. Potentially we could get this to share the space used by something else in the future, but this is one more step on the way to removing the gfs2_dinode_host structure. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
