x86/PCI/VMD: Use untracked irq handler There is no way to know which device in a VMD triggered an interrupt without invoking every registered driver's actions. This uses the untracked irq handler so that a less used device does not trigger spurious interrupt. We have been previously recommending users to enable "noirqdebug", but do not want to force a system setting just to keep this domain functional.
