ocfs2: Call refcount tree remove process properly.
Now with xattr refcount support, we need to check whether
we have xattr refcounted before we remove the refcount tree.
Now the mechanism is:
1) Check whether i_clusters == 0, if no, exit.
2) check whether we have i_xattr_loc in dinode. if yes, exit.
2) Check whether we have inline xattr stored outside, if yes, exit.
4) Remove the tree.
