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).
