Store the vid used on the bridge in the flow_offload_tuple, so it can be used later to identify fdb entries that relate to the tuple. The bridge_vid member is added to the structures nft_forward_info, nf_flow_route and flow_offload_tuple. It can now be passed from net_device_path->bridge.vlan_id to flow_offload_tuple->out.bridge_vid.
