This bug is marked as fixed by commit:
net: core: netlink: add helper refcount dec and lock function

net: sched: extend Qdisc with rcu
net: sched: rename qdisc_destroy() to qdisc_put()
net: sched: use Qdisc rcu API instead of relying on rtnl lock
But I can't find it in any tested tree for more than 90 days.
