MEDIUM: xprt-quic: finalize app layer initialization after ALPN nego

The app layer is initialized after the handshake completion by the XPRT
stack. Call the finalize operation just after that.

Remove the erroneous call to finalize by the mux in the TPs callback as
the app layer is not yet initialized at this stage.

This should fix the missing H3 settings currently not emitted by
haproxy.
