If a device does not own a resource then we don't need to disable it. This resolves the case where an Intel IGD device can be configured to disable decode of VGA memory but we still need the arbiter to handle VGA I/O port routing. When the IGD device is in conflict, only PCI_COMMAND_IO should be disabled since VGA memory does not require arbitration on this device.
