rbd: Fix mirror_image_get_status in rbd python bindings

When retrieving the status of a mirrored image from the Python rbd
library, a TypeError is raised.

*To Reproduce:*

Set up two Ceph clusters for block storage, and configure image
mirroring between their pools.  Create a least one image with mirroring
enabled, then run the following script on either cluster (once the image
exists everywhere):

```python
import rados, rbd

CONF_PATH = "YOUR-CONF-PATH"
POOL_NAME = "YOUR-POOL-NAME"
IMAGE_LABEL = "YOUR-IMAGE-LABEL"

with rados.Rados(conffile=CONF_PATH) as cluster:
  with cluster.open_ioctx(POOL_NAME) as ioctx:
    with rbd.Image(ioctx, IMAGE_LABEL) as image:
      image.mirror_image_get_status()
```

This will result in the following stack trace:

```
Traceback (most recent call last):
