Eric Dumazet e6c540bf97 net: sched: avoid writing on noop_qdisc ...

[ Upstream commit f98ebd47fd ]

While noop_qdisc.gso_skb and noop_qdisc.skb_bad_txq are not used
in other places, it seems not correct to overwrite their fields
in dev_init_scheduler_queue().

noop_qdisc is essentially a shared and read-only object, even if
it is not marked as const because of some implementation detail.
