vmm: Don't put a VFIO device behind the vIOMMU by default

Browse Source 
With some of the factorization that happened to be able to support VFIO
hotplug, one mistake was made. In case a vIOMMU is created through a
virtio-iommu device, and no matter the "iommu" option value from the
VFIO device parameter, the VFIO device was always placed behind the
virtual IOMMU.

This commit fixes this wrong behavior by making sure the device
configuration is taken into account to decide if it should be attached
or not to the virtual IOMMU.
