    ndctl, create-namespace: include dax info in operation result
    
    When modifying or creating a namespace in "dax" mode, include the
    device-dax information so that resulting character device is included in
    the output.
    
    Before:
    # ndctl create-namespace --reconfig=namespace1.0 --mode=dax --force
    {
      "dev":"namespace1.0",
      "mode":"dax",
      "size":4225761280,
      "uuid":"55082055-70f8-40eb-b131-d59f6f537df5"
    }
    
    After:
    # ndctl create-namespace --reconfig=namespace1.0 --mode=dax --force
    {
      "dev":"namespace1.0",
      "mode":"dax",
      "size":4225761280,
      "uuid":"1ccc310a-04af-4a57-88a4-6011c2825b95",
      "daxregion":{
        "id":1,
        "size":4225761280,
        "align":2097152,
        "devices":[
          {
            "chardev":"dax1.0",
            "size":4225761280
          }
        ]
      }
    }
