pkt_sched: fq: avoid hang when quantum 0
commit 3725a269815ba6dbb415feddc47da5af7d1fac58 upstream.
Configuring fq with quantum 0 hangs the system, presumably because of a
non-interruptible infinite loop. Either way quantum 0 does not make sense.
Reproduce with:
sudo tc qdisc add dev lo root fq quantum 0 initial_quantum 0
ping 127.0.0.1
