Peter Zijlstra 32d4fd5751 cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE
Commit c227233ad6 ("intel_idle: enable interrupts before C1 on
Xeons") wrecked intel_idle in two ways:

 - must not have tracing in idle functions
 - must return with IRQs disabled

Additionally, it added a branch for no good reason.
