rust: drm: fix GEM object pointer safety docs

IntoGEMObject::from_raw() receives a pointer to struct drm_gem_object,
not a pointer to Self. The previous documentation used Self even though
the function argument is the embedded GEM object pointer.

However, the pointer must not be any arbitrary valid drm_gem_object. The
implementations recover Self with container_of(), so the GEM object must
be embedded in a valid Self instance. This patch documents that requirement
explicitly.
