[PATCH] ndctl, create-namespace: include dax info in operation result

[PATCH] ndctl, create-namespace: include dax info in operation result

[Dan Williams]

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
      }
    ]
  }
}
