ocfs2: Proper cleanup in case of error in ocfs2_register_hb_callbacks()

Browse Source 
If ocfs2_register_hb_callbacks() succeeds on its first callback but fails
its second, it doesn't release the first on the way out. Fix that.

While we're at it, o2hb_unregister_callback() never returns anything but
0, so let's make it void.
