net_sched: do not reprogram a timer about to expire
qdisc_watchdog_schedule_range_ns() can use the newly added slack
and avoid rearming the hrtimer a bit earlier than the current
value. This patch has no effect if delta_ns parameter
is zero.
Note that this means the max slack is potentially doubled.
