[PATCH] vfio: Fix spapr vfio compile on some OS's

[Anatoly Burakov]

From: "Burakov, Anatoly" <anatoly.burakov@intel.com>

Some compilers require definition of vfio_iommu_spapr_tce_ddw_info
before its use in vfio_iommu_spapr_tce_info, so move tce_info
definition below tce_ddw_info.

Fixes: 45385235aece ("vfio: fix compile on older kernels")
