[PATCH v8 net-next 03/15] netfilter: flow: remove hw_outdev, out.hw_ifindex and out.hw_ifidx

[Eric Woudstra <ericwouds@gmail.com>]

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
