timers: Simplify code in run_local_timers()
The logic for raising a softirq the way it is implemented right now, is readable for two timer bases. When increasing the number of timer bases, code gets harder to read. With the introduction of the timer migration hierarchy, there will be three timer bases. Therefore restructure the code to use a loop. No functional change.
