powerpc/powernv/iov: Don't add VFs to iommu group during PE config 



In pnv_ioda_setup_vf_PE() we register an iommu group for the VF PE
then call pnv_ioda_setup_bus_iommu_group() to add devices to that group.
However, this function is called before the VFs are scanned so there's
no devices to add.
