Stefano Garzarella 2a7e48dc38 vdpa/mlx5: fix param validation in mlx5_vdpa_get_config()
commit dcfde1635e upstream.

It's legal to have 'offset + len' equal to
sizeof(struct virtio_net_config), since 'ndev->config' is a
'struct virtio_net_config', so we can safely copy its content under
this condition.
