Eric Dumazet 37314363cd pkt_sched: move the sanity test in qdisc_list_add() 
The WARN_ON(root == &noop_qdisc)) added in qdisc_list_add()
can trigger in normal conditions when devices are not up.
It should be done only right before the list_add_tail() call.

Fixes: e57a784d8c ("pkt_sched: set root qdisc before change() in attach_default_qdiscs()")
