Shankari Anand 2c32a5122a rust: miscdevice: clarify invariant for MiscDeviceRegistration 
[ Upstream commit b9ff1c2a26 ]

Reword and expand the invariant documentation for `MiscDeviceRegistration`
to clarify what it means for the inner device to be "registered".
It expands to explain:
- `inner` points to a `miscdevice` registered via `misc_register`.
- This registration stays valid for the entire lifetime of the object.
- Deregistration is guaranteed on `Drop`, via `misc_deregister`.
