time: hrtimer: Introduce hrtimer_next_event_without()
The next set of changes will need to compute the time to the next hrtimer event over all hrtimers except for the scheduler tick one. To that end introduce a new helper function, hrtimer_next_event_without(), for computing the time until the next hrtimer event over all timers except for one and modify the underlying code in __hrtimer_next_event_base() to prepare it for being called by that new function. No intentional changes in functionality. Signed-off-by: Rafael J.
