net_sched: check noop_qdisc before qdisc_hash_add()
Dmitry reported a crash when injecting faults in
attach_one_default_qdisc() and dev->qdisc is still
a noop_disc, the check before qdisc_hash_add() fails
to catch it because it tests NULL. We should test
against noop_qdisc since it is the default qdisc
at this point.
Fixes: 59cc1f61f09c ("net: sched: convert qdisc linked list to hashtable")
