[DEBUG]: sk_forward_alloc assertion failures

["David S. Miller" <davem@davemloft.net>]

Anton, can you and the other IBM folks who can reproduce
the problem give this test patch a whirl?

Herbert and I aren't exactly sure what the exact sequence
of events is that causes the problem, but we do know that
this code is highly suspect.

[ BTW, Herbert, it just occurred to me that these adjustments
  are incorrect for the skb->data pulling case since we really
  aren't liberating the data. ]

Thanks.
