net: ipv4: Don't crash if passing a null sk to ip_do_redirect.
Commit e2d118a1cb5e ("net: inet: Support UID-based routing in IP
protocols.") made ip_do_redirect 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.
Fixes: e2d118a1cb5e ("net: inet: Support UID-based routing in IP protocols.")
