Currently, when x2apic is not enabled, interrupt remapping will be enabled in init_dmars(), where it is too late to remap ioapic interrupts, that is, ioapic interrupts are really in compatibility mode, not remappable mode. This patch always enables interrupt remapping before ioapic setup, it guarantees all interrupts will be remapped when interrupt remapping is enabled. Thus it doesn't need to set the compatibility interrupt bit.
