Jamal Hadi Salim d837fbee92 net/sched: qfq: Use cl_is_active to determine whether class is active in qfq_rm_from_ag ...

This is more of a preventive patch to make the code more consistent and
to prevent possible exploits that employ child qlen manipulations on qfq.
use cl_is_active instead of relying on the child qdisc's qlen to determine
class activation.
