pkt_sched: Fix dev_graft_qdisc() locking
During dev_graft_qdisc() dev is deactivated, so qdisc_root_lock() returns wrong lock of noop_qdisc instead of qdisc_sleeping. Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
