net: Make skb->skb_iif always track skb->dev
Make it follow device decapsulation, from things such as VLAN and
bonding.
The stuff that actually cares about pre-demuxed device pointers, is
handled by the "orig_dev" variable in __netif_receive_skb(). And
the only consumer of that is the po->origdev feature of AF_PACKET
sockets.
