Wrong source address used for IPv6 notify messages

The source address field of 'newnotify' was not updated from the
default (0.0.0.0) when the destination address was an IPv6 address.
This resulted in the messages failing to be sent.  Set the source
address to :: when the destination address is an IPv6 address.
