[PATCH] rust: drm: fix GEM object pointer safety docs

[Yilin Chen]

IntoGEMObject::from_raw() takes a drm_gem_object pointer.

Its Safety docs described the argument as a pointer to Self, which does
not match the function signature. Update the docs to point to the actual 
pointer type accepted by the API.
