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().
