Get network the peer connected through.
Returns Network::NET_ONION for inbound onion connections, and CNetAddr::GetNetClass() otherwise. The latter cannot be used directly because it doesn't detect the former, and it's not the responsibility of the CNetAddr class to know the actual network a peer is connected through.
