ocfs2: Attach xattr clusters to refcount tree.
In ocfs2, when xattr's value is larger than OCFS2_XATTR_INLINE_SIZE, it will be kept outside of the blocks we store xattr entry. And they are stored in a b-tree also. So this patch try to attach all these clusters to refcount tree also. Signed-off-by: Tao Ma <tao.ma@oracle.com>
