MEDIUM: quic: qc_requeue_nacked_pkt_tx_frms() rework

This function is used to requeue the TX frames from TX packets which have
been detected as lost. The modifications consist in avoiding resending frames from
duplicated frames used to probe the peer. This is useless. Only the original
frames loss must be taken into an account because detected as lost before
the retransmitted frames. If these latter are also detected as lost, other
duplicated frames would have been retransmitted before their loss detection.
