infinite loop, relay through self p2p addresses

[ci-work]

often see gateways which are relayed through themselves, and compounding issue of other gateways relayed through a gateway which is relayed through itself, today there are quite a few:

multi cases, where one relayed gateway is relayed through a circular relay:
