Daniel Lezcano suggested removing CPUIDLE_FLAG_TIME_INVALID because
no states enable interrupts, and so cpuidle can always measure valid
residency time.  That turns out not to be un-true since x86 HALT is
invoked with interrupts enabled.  But looking at the code more closely,
Daniel's suggestion of simply removing the CPUIDLE_FLAG_TIME_INVALID
is actually an improvement over the workaround that we are currently using.
