net/sched: sch_fq_codel: annotate data-races from fq_codel_dump_class_stats()

Browse source

fq_codel_dump_class_stats() acquires qdisc spinlock only when requested
to follow flow->head chain.

As we did in sch_cake recently, add the missing READ_ONCE()/WRITE_ONCE()
annotations.

Fixes: edb09eb17e ("net: sched: do not acquire qdisc spinlock in qdisc/class stats dump")
