BUG/MINOR: mux-h2: condition the processing of 8441 extension to global setting

Browse Source 
When rfc8441 (extended connect) is disabled via
h2-workaround-bogus-websocket-clients, we properly refrain from
advertising support for extended connect, but we should also ignore
the incoming setting, otherwise it can remain enabled if the client
advertises it.

This should be backported to stable versions.
