From: Ying Gao <ying01....@samsung.com>

If suspend is executed during vsock communication and the
socket is reset, the original socket will be unusable after resume.

Judge the value of vdev->priv in function virtio_vsock_vqs_del,
only when the function is invoked by virtio_vsock_remove,
all vsock connections will be reset.
