[PATCH] drm/nouveau: Resolve the issue of VGA not detecting disconnection

[2564278112@qq.com]

From: Wang Jiang <jiangwang@kylinos.cn>

When using the GT730, I found that the VGA could recognize when it was plugged in,
but could not detect when it was disconnected.
The reason is that the polled flag for the connector is missing DRM_CONNECTOR_POLL_DISCONNECT.
