    ctdb-daemon: When releasing an IP, update PNN in callback
    
    When an error occurs so an IP address is not released then the PNN in
    the VNN is currently incorrectly updated.
    
    Instead, update the PNN in the callback when the release is
    successful.  Also, explicitly update the PNN on redundant releases.
