Subject: [PATCH 11/14] pkt_sched: Use qdisc_requeue() wrapper instead of
	open-coding.

Replace __skb_queue_head() and __skb_queue_tail() to sch->requeue list
with qdisc_requeue(). This change adds btw. updates of sch->q.qlen and
other stats, and uses __skb_queue_head() everywhere, which is proper
replacement for qdisc->ops->requeue() previously used here.
