Subject: [net-next PATCH 1/3] qdisc: adjustments for API allowing skb list
	xmits

Minor adjustments for merge commit 53fda7f7f9e (Merge branch 'xmit_list')
that allows us to work with a list of SKBs.

Update code doc to function sch_direct_xmit().

In handle_dev_cpu_collision() use kfree_skb_list() in error handling.
