BUG/MINOR: mux-quic: prevent a crash in session_free on mux.destroy

Implement qc_destroy. This callback is used to quickly release all MUX
resources.

session_free uses this callback. Currently, it can only be called if
there was an error during connection initialization. If not defined, the
process crashes.
