net_sched: add qdisc_watchdog_schedule_range_ns()
Some packet schedulers might want to add a slack
when programming hrtimers. This can reduce number
of interrupts and increase batch sizes and thus
give good xmit_more savings.
This commit adds qdisc_watchdog_schedule_range_ns()
helper, with an extra delta_ns parameter.
Legacy qdisc_watchdog_schedule_n() becomes an inline
passing a zero slack.
