[v5,net-next,02/14] netfilter: flow: remove hw_outdev, out.hw_ifindex and out.hw_ifidx

Commit Message

Now always info->outdev == info->hw_outdev, so the netfilter code can be
further cleaned up by removing:
 * hw_outdev from struct nft_forward_info
 * out.hw_ifindex from struct nf_flow_route
 * out.hw_ifidx from struct flow_offload_tuple
