[PATCH net-next 01/16] ipv4: Fix ip_local_out_sk by passing the sk into __ip_local_out_sk

["Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>]

In the rare case where sk != skb->sk ip_local_out_sk arranges
to call dst->output differently if the skb is queued or not.
This is a bug.

Fix this bug by passing the sk parameter of ip_local_out_sk through
from ip_local_out_sk to __ip_local_out_sk (skipping __ip_local_out).

Fixes: 7026b1ddb6b8 ("netfilter: Pass socket pointer down through okfn().")
