x86: Check irq_remapped instead of remapping_enabled in destroy_irq()
Russ Anderson reported:
| There is a regression that is causing a NULL pointer dereference
| in free_irte when shutting down xpc. git bisect narrowed it down
| to git commit d585d06(intr_remap: Simplify the code further), which
| changed free_irte(). Reverse applying the patch fixes the problem.
We need to use irq_remapped() for each irq instead of checking only
intr_remapping_enabled as there might be non remapped irqs even when
remapping is enabled.
[ tglx: use cfg instead of retrieving it again. Massaged changelog ]
