rec: Don't parse the QName in the packet cache if we already have it

When `gettag()` or protobuf are enabled, we have already parsed the
qname, qtype and qclass so pass them to the Packet Cache instead of
parsing them again.
Don't parse them several times if we have more than one match from
the cache either.
