To be fully correct, an iterator has an undefined value when something
like skb_queue_walk() naturally terminates.

This will actually matter when SKB queues are converted over to
list_head.

Formalize what this code ends up doing with the current
implementation.

I don't think this patch is really needed for -stable without the SKB
queue convertion, but okay.

I'll drop it. I'm not sure why this sctp patch wasn't filtered out as
davem deals with net/. Sorry for the noise.
