reference.docx: fix validation error on cnfStyle

Error from OOXMLValidator:
```
  {
        "Description": "The required attribute 'val' is missing.",
        "Path": {
            "NamespacesDefinitions": [
                "xmlns:w=\"http://schemas.openxmlformats.org/wordprocessingml/2006/main\""
            ],
            "Namespaces": {

            },
            "XPath": "/w:document[1]/w:body[1]/w:tbl[1]/w:tr[1]/w:trPr[1]/w:cnfStyle[1]",
            "PartUri": "/word/document.xml"
        },
        "Id": "Sch_MissRequiredAttribute",
        "ErrorType": "Schema"
    },
```

This is a bitmask where the first bit means 'first row', which is set as
an attribute already.
