net_sched: prio: use qdisc_dequeue_peeked
commit 07bd8df5df4369487812bf85a237322ff3569b77 (sch_sfq: fix peek() implementation) changed sfq to use generic peek helper. This makes HFSC complain about a non-work-conserving child qdisc, if prio with sfq child is used within hfsc: hfsc peeks into prio qdisc, which will then peek into sfq. returned skb is stashed in sch->gso_skb. Next, hfsc tries to dequeue from prio, but prio will call sfq dequeue directly, which may return NULL instead of previously peeked-at skb. Have prio call qdisc_dequeue_peeked, so sfq->dequeue() is not called in this case. Cc: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.
