[PATCH 07/11] hw/virtio/vhost-vsock: Include missing 'virtio/virtio-bus.h' header

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Instead of having "virtio/virtio-bus.h" implicitly included,
explicit it, to avoid when rearranging headers:

  hw/virtio/vhost-vsock-common.c: In function ‘vhost_vsock_common_start’:
  hw/virtio/vhost-vsock-common.c:51:5: error: unknown type name ‘VirtioBusClass’; did you mean ‘VirtioDeviceClass’?
     51 |     VirtioBusClass *k = VIRTIO_BUS_GET_CLASS(qbus);
        |     ^~~~~~~~~~~~~~
        |     VirtioDeviceClass
  hw/virtio/vhost-vsock-common.c:51:25: error: implicit declaration of function ‘VIRTIO_BUS_GET_CLASS’; did you mean ‘VIRTIO_DEVICE_CLASS’? [-Werror=implicit-function-declaration]
     51 |     VirtioBusClass *k = VIRTIO_BUS_GET_CLASS(qbus);
        |                         ^~~~~~~~~~~~~~~~~~~~
        |                         VIRTIO_DEVICE_CLASS
