Lion Ackermann 489422e2be net: sched: fix ordering of qlen adjustment
commit 5eb7de8cd5 upstream.

Changes to sch->q.qlen around qdisc_tree_reduce_backlog() need to happen
_before_ a call to said function because otherwise it may fail to notify
parent qdiscs when the child is about to become empty.
