support EDE 24 (Invalid Data)

Browse source 
Extended DNS Error 24 (Invalid Data) is returned when the server cannot
answer data for a zone it is configured for. This occurs typically when
an authoritative server does not have loaded the DB of a configured
zone, or a secondary server zone is expired.

See RFC 8914 section 4.25.
