drm/nouveau/kms/nv50: request vblank events for commits that send completion events
This somehow fixes an issue where sync-to-vblank longer works correctly after resume from suspend. From a HW perspective, we don't need the IRQs turned on to be able to detect flip completion, so it's assumed that this is required for the voodoo in the core DRM vblank core.
