Summary
sch_htb: make htb_qlen_notify() idempotent
Details

In the Linux kernel, the following vulnerability has been resolved:

schhtb: make htbqlen_notify() idempotent

htbqlennotify() always deactivates the HTB class and in fact could trigger a warning if it is already deactivated. Therefore, it is not idempotent and not friendly to its callers, like fqcodeldequeue().

Let's make it idempotent to ease qdisctreereduce_backlog() callers' life.
