resolved_addr_set_suggested() cannot succeed

This code will always trigger the BUG:

  if (BUG(tor_addr_family(addr) != AF_INET ||
          tor_addr_family(addr) != AF_INET6)) {
    return;
  }

Maybe this should be &&, not ||?

Possibly related to #40032 (closed), possibly not.

Found via a compiler warning on travis.
