pkt_sched: Remove smp_wmb() in qdisc_watchdog()
While implementing a TCQ_F_THROTTLED flag there was used an smp_wmb() in qdisc_watchdog(), but since this flag is practically used only in sch_netem(), and since it's not even clear what reordering is avoided here (TCQ_F_THROTTLED vs. __QDISC_STATE_SCHED?) it seems the barrier could be safely removed.
