Ondřej Surý f82c6f0cba Temporarily remove TCP fallback after UDP timeouts ... The retry path in resquery_send() that flipped DNS_FETCHOPT_TCP on a query whose dispatch had already been bound as UDP in fctx_query() had no effect on the transport actually used, but did leave a stale TCP bit visible to downstream consumers (dnstap framing, cookie checks, the AUTHORITY-NS spoofability guard). The ineffective code has been removed from resquery_send(). The TCP fallback functionality will be corrected and restored in the next commit.
