GEM helper libraries use struct drm_driver.gem_create_object to let drivers override GEM object allocation. On failure, the call returns NULL. Change the semantics to make the calls return a pointer-encoded error. This aligns the callback with its callers. Fixes the ingenic driver, which already returns an error pointer. Also update the callers to handle the involved types more strictly.
