Lorenzo Colitti 6eca888614 net: ipv4: Don't crash if passing a null sk to ip_rt_update_pmtu. ...

Commit e2d118a1cb ("net: inet: Support UID-based routing in IP
protocols.") made __build_flow_key call sock_net(sk) to determine
the network namespace of the passed-in socket. This crashes if sk
is NULL.

Fix this by getting the network namespace from the skb instead.
