core/dev: do not ignore dmac in dev_forward_skb()
commit 06a23fe31ca3
("core/dev: set pkt_type after eth_type_trans() in dev_forward_skb()")
and refactoring 64261f230a91
("dev: move skb_scrub_packet() after eth_type_trans()")
are forcing pkt_type to be PACKET_HOST when skb traverses veth.
which means that ip forwarding will kick in inside netns
even if skb->eth->h_dest != dev->dev_addr
Fix order of eth_type_trans() and skb_scrub_packet() in dev_forward_skb()
and in ip_tunnel_rcv()
