sched: fix potential deflated frequency estimation during IRQ handling
Time between mark_start of idle task and IRQ handler entry time is CPU
cycle counter stall period. Therefore it's inappropriate to include such
duration as part of sample period when we do frequency estimation.
Fix such suboptimality by replenishing idle task's CPU cycle counter
upon IRQ entry and using irqtime as time delta.
