api-ref: wrong parameter description in os-volume-attachments.inc

[Takashi Natsume]

In the following APIs, the 'volume_id' parameters are not body parameters. They are path parameters.

- GET /servers/{server_id}/os-volume_attachments/{volume_id}
- DELETE /servers/{server_id}/os-volume_attachments/{volume_id}

    api-ref: Fix parameters for os-volume-attachments.inc

    In the following APIs, the 'volume_id' parameters are
    'path' parameters. So fix them.

    - GET /servers/{server_id}/os-volume_attachments/{volume_id}
    - DELETE /servers/{server_id}/os-volume_attachments/{volume_id}

    In addition, the descriptions of the parameters are amended.
