[ACPI] fix pnpacpi regression resulting from ACPICA 20051117
In ACPICA 20051117, acpi_walk_resources() started sending ACPI_RESOURCE_TYPE_END_TAG to the callback routine which wasn't prepared for it, causing _CRS to fail and PnPACPI to not recognize any devices: pnp: ACPI device : hid PNP0C02 pnp: PnPACPI: unknown resource type 7 pnp: PnPACPI: METHOD_NAME__CRS failure for PNP0c02 Signed-off-by: Len Brown <len.brown@intel.com>
