====================
net: vrf: Fixup PKTINFO to return enslaved device index

Applications such as OSPF and BFD need the original ingress device not
the VRF device; the latter can be derived from the former. To that end
move the packet intercept from an rx handler that is invoked by
__netif_receive_skb_core to the ipv4 and ipv6 receive processing.

IPv6 already saves the skb_iif to the control buffer in ipv6_rcv. Since
the skb->dev has not been switched the cb has the enslaved device. Make
the same happen for IPv4 by adding the skb_iif to inet_skb_parm and set
it in ipv4 code after clearing the skb control buffer similar to IPv6.
From there the pktinfo can just pull it from cb with the PKTINFO_SKB_CB
cast.
