s/vfio_iommu/vfio_container/, but yes. I actually have a series that
does this (also for a few other methods), but this requires exposing
vfio_container and vfio_iommu_group outside of vfio.c. Given that this
series is big enough I decided to skip it for now, but that plus a few
other changes will eventually simplify the group lookups in
vfio_iommu_type1.c.
