drm/virtio: fix unblank
When going through a disable/enable cycle without changing the
framebuffer the optimization added by commit 3954ff10e06e ("drm/virtio:
skip set_scanout if framebuffer didn't change") causes the screen stay
blank. Add a bool to force an update to fix that.
v2: use drm_atomic_crtc_needs_modeset() (Daniel).
