net: prevent unintended retries upon receiving an empty answer response from the DNS server.
CL https://golang.org/cl/37879 migrates DNS message parsing to the golang.org/x/net/dns/dnsmessage package. However, during the modification of the "lame referral" error check introduced by CL https://golang.org/cl/22428, a condition was overlooked. This omission results in unexpected retries when a DNS server returns an empty response (not an invalid response, but one that includes an additional section).
Fixes #57697
Fixes #64783
