netfilter: Use l3mdev flow key when re-routing mangled packets
Commit 40867d74c374 ("net: Add l3mdev index to flow struct and avoid oif
reset for port devices") introduces a flow key specific for layer 3
domains, such as a VRF master device. This allows for explicit VRF domain
selection instead of abusing the oif flow key.
Update ip[6]_route_me_harder() to make use of that new key when re-routing
mangled packets within VRFs instead of setting the flow oif, making it
consistent with other users.
