Subject: fix: usr: Stop caching lack of EDNS support
X-Git-Tag: v9.21.7~2

fix: usr: Stop caching lack of EDNS support

`named` could falsely learn that a server doesn't support EDNS when
a spoofed response was received; that subsequently prevented DNSSEC
lookups from being made.  This has been fixed.
