introduce backup_classid to struct skbuff,
we can use it to backup sk_classid when net_ns switch.

Sorry, no new sk_buff members unless there is absolutely not other
sk_buff is too big as-is.
To get what you want fix the dev_forward_skb() call. But its
not clear to me why you would expect the sock info to be propagated
like this. It seems like an incorrect assumption or a misunderstanding
somewhere. If the virtual link was a physical link you wouldn't expect
to know anything about the senders socket.
