net_sched: get rid of unnecessary dev_qdisc_reset()
Resetting old qdisc on dev_queue->qdisc_sleeping in
dev_qdisc_reset() is redundant, because this qdisc,
even if not same with dev_queue->qdisc, is reset via
qdisc_put() right after calling dev_graft_qdisc() when
hitting refcnt 0.
This is very easy to observe with qdisc_reset() tracepoint
and stack traces.
