[PATCH 6/7] qemuBuildDeviceVideoStr: Move logic wrapping qemuBuildVirtioDevStr() into qemuDeviceVideoGetModel()

[Michal Privoznik]

We want to call qemuBuildVirtioDevStr() from
qemuBuildDeviceVideoStr() but only for some models (currently
"virtio-gpu" and "vhost-user-gpu"), not all of them. Move this
logic into qemuDeviceVideoGetModel() because this logic will be
refined.
