duplicates of the following [1] syzbot managed to install fq_pie with a zero TCA_FQ_PIE_QUANTUM, thus triggering infinite loops. Use limits similar to sch_fq, with commits 3725a269815b ("pkt_sched: fq: avoid hang when quantum 0") and d9e15a273306 ("pkt_sched: fq: do not accept silly TCA_FQ_QUANTUM") [1] watchdog: BUG: soft lockup - CPU#0 stuck for 26s!
