drm/nouveau/kms/gv100-: fix spurious window immediate interlocks
Cursor position updates were accidentally causing us to attempt to interlock window with window immediate, and without a matching window immediate update, NVDisplay could hang forever in some circumstances. Fixes suspend/resume on (at least) Quadro RTX4000 (TU104). Reported-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
