[PATCH 2/2] ethdev: include device name in telemetry list output

[Chengwen Feng]

The /ethdev/list telemetry endpoint currently returns only port IDs
as integers. Enhance it to return strings in "ID    NAME" format so
users can identify ports by name directly from the telemetry output.

Original:
  {
    "/ethdev/list": [
      0,
      1
    ]
  }

After this commit:
  {
    "/ethdev/list": [
      "0    0000:7d:00.0",
      "1    0000:7d:00.1"
    ]
  }
