QUIC: cleanup send context properly. The patch resets ctx->frames queue, which may contain frames. It was possible that congestion or amplification limits prevented all frames to be sent. Retransmitted frames could be accounted twice as inflight: first time in ngx_quic_congestion_lost() called from ngx_quic_resend_frames(), and later from ngx_quic_discard_ctx().
