net: sched: fix missing free per cpu on qstats
[ Upstream commit 73c20a8b7245273125cfe92c4b46e6fdb568a801 ]
When a qdisc is using per cpu stats (currently just the ingress
qdisc) only the bstats are being freed. This also free's the qstats.
Fixes: b0ab6f92752b9f9d8 ("net: sched: enable per cpu qstats")
