Borislav Petkov (AMD) c8f5caec3d cpuidle: haltpoll: Do not enable interrupts when entering idle 
The cpuidle drivers' ->enter() methods are supposed to be IRQ invariant:

  5e26aa9339 ("cpuidle/poll: Ensure IRQs stay disabled after cpuidle_state::enter() calls")
  bb7b112585 ("cpuidle: Move IRQ state validation")

Do that in the haltpoll driver too.

Fixes: 5e26aa9339 ("cpuidle/poll: Ensure IRQs stay disabled after cpuidle_state::enter() calls")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218245
