hrtimer: Re-arrange hrtimer_interrupt()

Browse source

Rework hrtimer_interrupt() such that reprogramming is split out into an
independent function at the end of the interrupt.

This prepares for reprogramming getting delayed beyond the end of
hrtimer_interrupt().

Notably, this changes the hang handling to always wait 100ms instead of
trying to keep it proportional to the actual delay. This simplifies the
state, also this really shouldn't be happening.
