vdpa: check for iova tree initialized at net_client_start
To map the guest memory while it is migrating we need to create the iova_tree, as long as the destination uses x-svq=on. Checking to not override it. The function vhost_vdpa_net_client_stop clear it if the device is stopped. If the guest starts the device again, the iova tree is recreated by vhost_vdpa_net_data_start_first or vhost_vdpa_net_cvq_start if needed, so old behavior is kept.
