sch_sfq: fix peek() implementation
[ Upstream commit 07bd8df5df4369487812bf85a237322ff3569b77 ] Since commit eeaeb068f139 (sch_sfq: allow big packets and be fair), sfq_peek() can return a different skb that would be normally dequeued by sfq_dequeue() [ if current slot->allot is negative ] Use generic qdisc_peek_dequeued() instead of custom implementation, to get consistent result.
