vdpa_sim: use max_iotlb_entries as a limit in vhost_iotlb_init
Commit bda324fd037a ("vdpasim: control virtqueue support") changed
the allocation of iotlbs calling vhost_iotlb_init() for each address
space, instead of vhost_iotlb_alloc().
With this change we forgot to use the limit we had introduced with
the `max_iotlb_entries` module parameter.
