From: Ying Gao <ying01.gao@xxxxxxxxxxx> In function virtio_vsock_probe, it initializes the variables "rx_buf_nr" and "rx_buf_max_nr", but in function virtio_vsock_restore it doesn't. Move the initizalition position into function virtio_vsock_vqs_start. Once executing s2r twice in a row without initializing rx_buf_nr and rx_buf_max_nr, the rx_buf_max_nr increased to three times vq->num_free, at this time, in function virtio_transport_rx_work, the conditions to fill rx buffer (rx_buf_nr < rx_buf_max_nr / 2) can't be met.
