For hierarchical qdisc like HTB, we currently only update its qlen
but leave its backlog as zero:
qdisc htb 1: dev eth0 root refcnt 2 r2q 10 default 1 direct_packets_stat 0
ver 3.17
Sent 172680457356 bytes 222469449 pkt (dropped 0, overlimits 123575834
requeues 0)
backlog 0b 72p requeues 0
This patchset makes backlog as accurate as qlen.
