Subject: drm/tegra: hub: Use state directly
Git-commit: b1a3dc0b85bde4d8d549ea3aa31106b599694f37
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Using drm_atomic_get_private_obj_state() after state has been swapped
will return old state.

Fixes: 0281c4149021 ("drm/tegra: hub: Use private object for global state")
