x86, vt-d: Fix the vt-d fault handling irq migration in the x2apic mode
commit 086e8ced65d9bcc4a8e8f1cd39b09640f2883f90 upstream.
In x2apic mode, we need to set the upper address register of the fault
handling interrupt register of the vt-d hardware. Without this
irq migration of the vt-d fault handling interrupt is broken.
