Subject: [PATCH v2] rust: device_id: replace incorrect word in safety documentation

The safety documentation incorrectly refers to `RawDeviceId` when
transmuting to `RawType`. This fixes the documentation to correctly
indicate that implementers must ensure layout compatibility with
`RawType`, not `RawDeviceId`.
