net: sch_fq: update flow delivery time on earlier EDT packet
When inserting an EDT packet with time before flow->time_next_packet,
update the flow and possibly queue next delivery time.
Reinsert the flow into the q->delayed rb-tree to position correctly
and to have fq_check_throttled set wake-up at the right next time.
Factor RB tree insertion out fq_flow_set_throttled to avoid open
coding twice.
EDT packets do not take precedence over queue rate limit. Skip this
new step if a queue limit is set. EDT packets do take precedence over
per-socket rate limits, as can be seen from fq_dequeue reading
sk_pacing_rate if !skb->tstamp.
With this change the so_txtime selftest sends packets in the expected
order.
