Exactly, keep the converted entry in skb, since we have to allocate
that anyway. And when there's no more entries coming from enumerator
the sequence number of final skb is adjusted to zero.

Not sure if I can finish it today, but I think I should have the
time by tomorrow. Unless you have time to do it before that, I'll
post a patch later this week. Will update the similar xfrm_policy
patch for that too, before sending it.
