pkt_sched: Manage qdisc list inside of root qdisc.
Idea is from Patrick McHardy. Instead of managing the list of qdiscs on the device level, manage it in the root qdisc of a netdev_queue. This solves all kinds of visibility issues during qdisc destruction. The way to iterate over all qdiscs of a netdev_queue is to visit the netdev_queue->qdisc, and then traverse it's list. The only special case is to ignore builting qdiscs at the root when dumping or doing a qdisc_lookup(). That was not needed previously because builtin qdiscs were not added to the device's qdisc_list.
