It is confusing and silly hiding a paramater so modify all of
the callers to pass in the appropriate socket or skb->sk if
no socket is known.

As stated in the comment at the top of this function (ip_queue_xmit()), skb->sk
can be different from sk. See also commit b0270e91014d ("ipv4: add a sock
pointer to ip_queue_xmit()").
Not sure if this change is right.
