[Intel-gfx] [PATCH] drm/atomic-helper: Really recover pre-atomic plane/cursor behavior

[Daniel Vetter]

I've fumbled this in

commit f02ad907cd9e7fe3a6405d2d005840912f1ed258
Author: Daniel Vetter <daniel.vetter at ffwll.ch>

    drm/atomic-helpers: Recover full cursor plane behaviour

and accidentally put the assignment for legacy_cursor_upate after the
atomic commit, where it is pretty useless.
