Thomas Zimmermann 657b5d916a drm: Return error codes from struct drm_driver.gem_create_object 
[ Upstream commit 4ff22f487f8c26b99cbe1678344595734c001a39 ]

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.
