server list --locked and --unlocked report same list

With python-openstackclient 6.6.0 and Python 3.12.7 (though confirmed around the office with a few others), `openstack server list --project <project> --locked` and `openstack server list --project <project> --unlocked` produce the same list (i.e. all) of instances in the project.

- Have tried specifying the minimum/specififed compute service API version:
  `os server list --project 19616f0d69cc4241b12e09b287a6cd46 --unlocked --os-compute-api-version 2.73`
- Have tried actually locking instances and listing, and both locked/unlocked modifiers always list all instances

e.g.:

```
openstack --version
openstack 6.6.0

python --version
Python 3.12.7

openstack server list --help | grep locked
                             [--locked | --unlocked] [--tags <tag>]
  --locked Only display locked servers (supported by --os-
  --unlocked Only display unlocked servers (supported by --os-

openstack server list --project 1961<RD>6cd46 --locked | wc -l
      15
openstack server list --project 1961<RD>6cd46 --unlocked | wc -l
      15

for i in $(openstack server list --project 1961<RD>6cd46 -c ID -f value);do openstack server show $i | grep -w locked;done
| locked | False |
| locked | False |
| locked | False |
| locked | False |
| locked | False |
| locked | False |
| locked | False |
| locked | False |
| locked | False |
| locked | False |
| locked | False |
```
