sch_drr: make drr_qlen_notify() idempotent
commit df008598b3a00be02a8051fde89ca0fbc416bd55 upstream.
drr_qlen_notify() always deletes the DRR class from its active list
with list_del(), therefore, it is not idempotent and not friendly
to its callers, like fq_codel_dequeue().
Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers'
life. Also change other list_del()'s to list_del_init() just to be
extra safe.
