commit 51cbb5242a41700a3f250ecfb48dcfb7e4375ea4 upstream.
As Helge reported for timerfd we have the same issue in itimers. We return
remaining time larger than the programmed relative time to user space in case
of CONFIG_TIME_LOW_RES=y. Use the proper function to adjust the extra time
added in hrtimer_start_range_ns().

Except for Kconfig.HZ. That needs a separate treatment.
