    ocfs2 mounts require a heartbeat region.  Use the new configfs_depend_item()
    facility to actually depend on them so they can't go away from under us.
    
    First, teach cluster/nodemanager.c to depend an item on the o2cb subsystem.
    Then teach o2hb_register_callbacks to take a UUID and depend on the
    appropriate region.  Finally, teach all users of o2hb to pass a UUID or
    NULL if they don't require a pin.
