MINOR: mux_quic: do not crash on unhandled QMux frame reception

Completes qmux_parse_frm() to ensure every frames allowed by QMux
protocol are listed. For now, nothing is implemented except a CHECK_IF()
to report such events.

This is necessary to prevent a crash on abort. Frames not supported by
QMux should already have been rejected prior via qmux_is_frm_valid().
