Fix DNS64 owner case after DNAME restart

Browse source 
When DNS64 filters a partially excluded AAAA RRset after a DNAME
restart, dns_message_findname() can return an existing message-owned
owner name while qctx->fname is released on the NXRRSET path.

Set owner case from the message-owned name used for attaching the
filtered rdataset, avoiding a stale alias to the released temporary
name.
