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.
The second part of the commit message is not that clear, do you mind
rephrasing it?

I would add a comment explaining why you are adding this check.

I am not familiar with freeze/resume, but I don't see any problems with
this patch.
Thank you,
