cpuidle: Check the sign of index in cpuidle_reflect()
Avoid calling the governor's ->reflect method if the state index
passed to cpuidle_reflect() is negative.
This allows the analogous check to be dropped from menu_reflect(),
so do that too, and ensures that arbitrary error codes can be
passed to cpuidle_reflect() as the index with no adverse
consequences.
