Value of '0' is treated equivalently to when it's not provided by the user. Reject an explicit '0' provided by the user as it would get ignored. In this rare case we can make the XML parser more strict, as libvirt would never format the '<acpi/>' element if the index is '0' thus there are no libvirt-generated XMLs we'd not load back, as of such this is identical to rejecting it in the validation phase.
