vmm: Add iommu=on|off option for --net

Browse Source 
Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a virtio-net device should be attached to this
virtual IOMMU or not. That's why we introduce an extra option "iommu"
with the value "on" or "off". By default, the device is not attached,
which means "iommu=off".
