resolved: properly handle LLMNR/TCP connection errors
The LLMNR spec suggests to do do reverse address lookups by doing direct LLMNR/TCP connections to the indicated address, instead of doing any LLMNR multicast queries. When we do this and the peer doesn't actually implement LLMNR this will result in a TCP connection error, which we need to handle. In contrast to most LLMNR lookups this will give us a quick response on whether we can find a suitable name. Report this as new transaction state, since this should mostly be treated like an NXDOMAIN rcode, except that it's not one.
