net_sched: update bstats in dequeue()
Class bytes/packets stats can be misleading because they are updated in enqueue() while packet might be dropped later. We already fixed all qdiscs but sch_atm. This patch makes the final cleanup. class rate estimators can now match qdisc ones. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
