ocfs2: make room for unwritten extents flag
Due to the size of our group bitmaps, we'll never have a leaf node extent record with more than 16 bits worth of clusters. Split e_clusters up so that leaf nodes can get a flags field where we can mark unwritten extents. Interior nodes whose length references all the child nodes beneath it can't split their e_clusters field, so we use a union to preserve sizing there.
