sockets: Plug memory leak in socket_address_flatten()

Browse Source 
socket_address_flatten() leaks a SocketAddress when its argument is
null.  Happens when opening a ChardevBackend of type 'udp' that is
configured without a local address.  Screwed up in commit bd269ebc due
to last minute semantic conflict resolution.  Spotted by Coverity.
