drm: fix fb refcount issue with atomic modesetting
After commit 027b3f8b ("drm/modes: stop handling framebuffer special") extra fb refs are left around when doing atomic modesetting. The problem is that the new drm_property_change_valid_get() does not return anything in the '**ref' parameter, which causes drm_property_change_valid_put() to do nothing. For some reason this doesn't cause problems with legacy API. Also, previously the code only set the 'ref' variable for fbs, with this patch the 'ref' is set for all objects.
