David Gibson ee0bf0e59b vfio: Remove unneeded union from VFIOContainer
Currently the VFIOContainer iommu_data field contains a union with
different information for different host iommu types.  However:
   * It only actually contains information for the x86-like "Type1" iommu
   * Because we have a common listener the Type1 fields are actually used
on all IOMMU types, including the SPAPR TCE type as well

In fact we now have a general structure for the listener which is unlikely
to ever need per-iommu-type information, so this patch removes the union.

In a similar way we can unify the setup of the vfio memory listener in
vfio_connect_container() that is currently split across a switch on iommu
type, but is effectively the same in both cases.

The iommu_data.release pointer was only needed as a cleanup function
which would handle potentially different data in the union.  With the
union gone, it too can be removed.
