[NETNS][IPV6] route6 - pass always a valid socket to ip6_dst_lookup

Browse source 
The ip6_dst_lookup receive a socket as parameter. In some part of the code
it is called with a NULL socket parameter. We want to rely on the socket
to retrieve the network namespace, so we always pass a valid socket in all
cases.
