commit 637543a8d6 upstream.
Current logic incorrectly uses the enum ioapic_irq_destination_types
to check the posted interrupt destination types. However, the value was
set using APIC_DM_XXX macros, which are left-shifted by 8 bits.
Fixes by using the APIC_DM_FIXED and APIC_DM_LOWEST instead.
Fixes: (fdcf756213 'KVM: x86: Disable posted interrupts for non-standard IRQs delivery modes')
