[PATCH 3/3] virtio: Define max_nr_ports to unsigned

[Amos Kong <akong@redhat.com>]

hw/virtio-serial-bus.c:
725 static int virtser_port_qdev_init(DeviceState *qdev, DeviceInfo *base)
726 {
...
730     int ret, max_nr_ports;
...
762     max_nr_ports = tswap32(port->vser->config.max_nr_ports);
763     if (port->id >= max_nr_ports) {

tswap32() returns an uint32_t variable.
