`authorization` variable is unused

Function creates the `authorization` object, but doesn't use it in the API call.
https://github.com/influxdata/iot-api-python/blob/main/api/devices.py#L148

Also, the API call doesn't contain the `desc_prefix` for the authorization.

Start at api/devices.py#L148 and inspect the function that creates the authorization object and makes the API call. Verify how that call should use authorization and include desc_prefix. Done means the request uses both values correctly; no tests are mentioned in the issue, so check the surrounding API code for the relevant validation path.
