A connection that has seen a HTTP major version now refuses any other major HTTP version in future responses. Previously, a HTTP/1.x connection would just silently accept HTTP/2 or HTTP/3 in the status lines as long as it had support for those built-in. It would then just lead to confusion and badness. Indirectly Spotted by CodeSonar which identified a duplicate assignment in this function. Add test 471 to verify
