net/sched: sch_htb: do not change sch->flags in htb_dump()
htb_dump() runs without holding qdisc spinlock.
It is illegal to touch sch->flags with non locked RMW,
as concurrent readers might see intermediate wrong values.
Set TCQ_F_OFFLOADED in control path (htb_init()) instead.
Fixes: d03b195b5aa0 ("sch_htb: Hierarchical QoS hardware offload")
