rust: device_id: replace incorrect word in safety documentation

Browse source 
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`.

Fixes: 9b90864bb4 ("rust: implement `IdArray`, `IdTable` and `RawDeviceId`")
