[PATCH] drm/vc4: fix error code in vc4_create_object()

[Dan Carpenter]

The ->gem_create_object() functions are supposed to return NULL if there
is an error.  None of the callers expect error pointers so returing one
will lead to an Oops.  See drm_gem_vram_create(), for example.

Fixes: c826a6e10644 ("drm/vc4: Add a BO cache.")
