[NET_SCHED]: Fix endless loops (part 2): "simple" qdiscs
Convert the "simple" qdiscs to use qdisc_tree_decrease_qlen() where necessary: - all graft operations - destruction of old child qdiscs in prio, red and tbf change operation - purging of queue in sfq change operation Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
