ocfs2: Move the call of ocfs2_hb_ctl into the stack glue.

Browse Source 
Take o2hb_stop() out of the o2cb code and make it part of the generic
stack glue as ocfs2_leave_group().  This also allows us to remove the
ocfs2_get_hb_ctl_path() function - everything to do with hb_ctl is now
part of stackglue.c.  o2cb no longer needs a ->hangup() function.

/*
* Hangup is a hack for tools compatibility. Older ocfs2-tools software
* expects the filesystem to call "ocfs2_hb_ctl" during unmount. This
* happens regardless of whether the DLM got started, so we can't do it
* in ocfs2_cluster_disconnect(). We bring the o2hb_stop() function into
* the glue and provide a "hangup" API for super.c to call.
*
* Other stacks will eventually provide a NULL ->hangup() pointer.
