Eugenio Pérez 5fde952bbd vhost: move iova_tree set to vhost_svq_start ...

Since we don't know if we will use SVQ at qemu initialization, let's
allocate iova_tree only if needed. To do so, accept it at SVQ start, not
at initialization.

This will avoid to create it if the device does not support SVQ.
