drm/rockchip: vop2: fix null pointer in plane_atomic_disable
If the vop2_plane_atomic_disable function is called with NULL as a
state, accessing the old_pstate runs into a null pointer exception.
However, the drm_atomic_helper_disable_planes_on_crtc function calls the
atomic_disable callback with state NULL.
Allow to disable a plane without passing a plane state by checking the
old_pstate only if a state is passed.
