Add early-boot-safety check to cond_resched()
Just to be safe, we should not trigger a conditional reschedule during
the early boot sequence. We've historically done some questionable
early on, and the safety warnings in __might_sleep() are generally
turned off during that period, so there might be problems lurking.
This affects CONFIG_PREEMPT_VOLUNTARY, which takes over might_sleep() to
cause a voluntary conditional reschedule.
