ocfs2: Remove fs dependency on ocfs2_heartbeat module
Now that the dlm exposes domain information to us, we don't need generic node up / node down callbacks. And since the DLM is only telling us when a node goes down unexpectedly, we no longer need to optimize away node down callbacks via the umount map. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
