ocfs2: Depend on configfs heartbeat items.
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.
