[NET_SCHED]: ingress: switch back to using ingress_lock
Switch ingress queueing back to use ingress_lock. qdisc_lock_tree now locks both the ingress and egress qdiscs on the device. All changes to data that might be used on both ingress and egress needs to be protected by using qdisc_lock_tree instead of manually taking dev->queue_lock. Additionally the qdisc stats_lock needs to be initialized to ingress_lock for ingress qdiscs. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
