hrtimer: Avoid re-evaluation when nothing changed
Most times there is no change between hrtimer_interrupt() deferring the rearm
and the invocation of hrtimer_rearm_deferred(). In those cases it's a pointless
exercise to re-evaluate the next expiring timer.
Cache the required data and use it if nothing changed.
