Lyude Paul 36b1ccbfa0 rust: drm: gem: Refactor IntoGEMObject::from_gem_obj() to as_ref()
There's a few issues with this function, mainly:

* This function -probably- should have been unsafe from the start. Pointers
  are not always necessarily valid, but you want a function that does
  field-projection for a pointer that can travel outside of the original
  struct to be unsafe, at least if I understand properly.
* *mut Self is not terribly useful in this context, the majority of uses of
  from_gem_obj() grab a *mut Self and then immediately convert it into a
  &'a Self. It also goes against the ffi conventions we've set in the rest
  of the kernel thus far.
* from_gem_obj() also doesn't follow the naming conventions in the rest of
  the DRM bindings at the moment, as_ref() would be a better name.

So, let's:

* Make from_gem_obj() unsafe
* Convert it to return &'a Self
* Rename it to as_ref()
* Update all call locations
