net: bridge: declare br_vlan_tunnel_lookup argument tunnel_id as __be64
The only caller of br_vlan_tunnel_lookup, br_handle_ingress_vlan_tunnel, extracts the tunnel_id from struct ip_tunnel_info::struct ip_tunnel_key:: tun_id which is a __be64 value. The exact endianness does not seem to matter, because the tunnel id is just used as a lookup key for the VLAN group's tunnel hash table, and the value is not interpreted directly per se. Moreover, rhashtable_lookup_fast treats the key argument as a const void *. Therefore, there is no functional change associated with this patch, just one to silence "make W=1" builds.
