* plugin/edns: remove truncating of question section on bad EDNS version
EDNS requests of "Unknown Version" removed the query section altogether.
Not sure why since this is not require (see [link](https://kb.isc.org/docs/edns-compatibility-dig-queries)
This cause issues with DNS solutions that uses this information (initial queried name, type and class) in order to route the response to the right client (e.g. PDNS).
The change here is to keep the inital query section as is.
