As I understand it, drm_gem_object_alloc() returns a referenced object.
drm_get_handle_create() also references the object, so the local
reference is no longer needed.

BUT, the handle is what we are returning from this function, so we
really don't want to dereference it... we just want to drop the local
reference on the object.
