[ Upstream commit 9cd3f4efc870463f17f6c29114c61fb6bfcaa291 ]
After successful call to drm_suballoc_manager_init() we should make sure to call drm_suballoc_manager_fini() as it may include some cleanup code even if we didn't start using it for real.
As we can abort init() early due to kvzalloc() failure, we should either explicitly call drm_suballoc_manager_fini() or, even better, postpone drm_suballoc_manager_init() once we finish all other preparation steps, so we can rely on fini() that will do cleanup.
