Fix getaddrinfo() handling in blocking resolver If getaddrinfo() fails, the first call setting the result will already free the resolver. Trying to access it afterwards will lead to a warning to the console from glib. getaddrinfo() shouldn't return NULL for the result list if it returns successful.
