oxide hardware switch-port status returns 500 error when querying unconfigured port

On the colo rack, we have both qsfp8 ports populated, but the qsfp9 ports are empty:

‣ ./oxide --profile colo-admin system hardware switch-port show-status | grep 'qsfp[89]'
qsfp8   true        true     a8:40:25:05:15:43  false    RS    up/LinkUp       Optical  Speed100G
qsfp9   false       -        -                  -        -     -               -        -
qsfp8   true        true     a8:40:25:05:0f:43  false    RS    up/LinkUp       Optical  Speed100G
qsfp9   false       -        -                  -        -     -               -        -

If we query qsfp8, we get a valid response:

However, if we query qsfp9 we get a 500 error:

error
Error Response: status: 500 Internal Server Error; headers: {"content-type": "application/json", "x-request-id": "598d70b2-76dd-465f-afe8-5d605aaf689f", "content-length": "124", "date": "Fri, 22 Nov 2024 20:05:31 GMT"}; value: Error { error_code: Some("Internal"), message: "Internal Server Error", request_id: "598d70b2-76dd-465f-afe8-5d605aaf689f" }

Start by reproducing the switch-port status command for the unconfigured qsfp9 port and trace the API path that handles the request. Compare it with the successful qsfp8 response; done means querying an unconfigured port no longer returns a 500 Internal Server Error.
