net: sched: fix dump qlen for sch_mq/sch_mqprio with NOLOCK subqueues
[ Upstream commit 2f23cd42e19c22c24ff0e221089b7b6123b117c5 ]
sch->q.len hasn't been set if the subqueue is a NOLOCK qdisc
in mq_dump() and mqprio_dump().
Fixes: ce679e8df7ed ("net: sched: add support for TCQ_F_NOLOCK subqueues to sch_mqprio")
