[PATCH] Fix TIF_POLLING_NRFLAG in ACPI idle routines

Commit 6f38ee2ebe42ecaf9128ab8513358faa5a4b175e broke the ACPI C2 and C3
sleep states, because it left TIF_POLLING_NRFLAG active even though
those states do not actually poll the reschedule flag at all.  As a
result, the CPU wouldn't get sent an IPI when it was to be woken up, and
would only notice that it had runnable processes on the next timer tick.
