net/core: dev_forward_skb() should clear skb_iif
While investigating another bug, I found that the code on the incoming path
in __netif_receive_skb will only set skb->skb_iif if it is already 0. When
dev_forward_skb() is used in the case of interfaces like veth, skb_iif may
already have been set. Making dev_forward_skb() cause the packet to look
like a newly received packet would seem to the the correct behaviour here,
as otherwise the wrong incoming interface can be reported for such a packet.
