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