rzg2l_du_vsp_get_drm_plane() scans all DRM planes for a matching pipe_index, but with multiple VSP instances two planes belonging to different VSPs can share the same index. Add a vsp pointer check so the search is scoped to the CRTC's own VSP instance.
No functional change for single-VSP platforms.
