sched: take account of irq preemption when calculating irqload delta
If irq raises while sched_irqload() is calculating irqload delta,
sched_account_irqtime() can update rq's irqload_ts which can be greater
than the jiffies stored in sched_irqload()'s context so delta can be
negative. This negative delta means there was recent irq occurence.
So remove improper BUG_ON().
