MdeModulePkg/IncompatiblePci: Use MAX_UINTN to match any IDs 

When the VendorId/DeviceId/RevisionId/SubsystemVendorId
/SubsystemDeviceId is MAX_UINTN, IncompatiblePciDeviceSupport
driver doesn't use it to match any IDs.
The patch fixes this bug.
Since PciBus driver always calls IncompatiblePciDeviceSupport
using IDs read from HW, MAX_UINTN is never passed to this
driver.
