BUG/MINOR: mux_quic: Dropped packet upon retransmission for closed streams

Browse Source 
We rely on the largest ID which was used to open streams to know if the
stream we received STREAM frames for is closed or not. If closed, we return the
same status as the one for a STREAM frame which  was a already received one for
on open stream.
