[patch 4/4] itimers: Handle relative timers with CONFIG_TIME_LOW_RES proper

[Thomas Gleixner]

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().
