Eric Dumazet ae6cfa6602 fq_codel: return non zero qlen in class dumps
commit aafddbf0cffeb790f919436285328c762279b5d4 upstream.

We properly scan the flow list to count number of packets,
but John passed 0 to gnet_stats_copy_queue() so we report
a zero value to user space instead of the result.

Fixes: 640158536632 ("net: sched: restrict use of qstats qlen")
