cpuidle/powernv: avoid double irq enable coming out of idle
Since e1689795a7 ("cpuidle: Add common time keeping and irq enabling"), cpuidle drivers are expected to return from ->enter with irqs disabled. Update the cpuidle-powernv snooze loop to disable irqs before returning. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
