vfio: Add explicit alignments in vfio_iommu_spapr_tce_create
The vfio_iommu_spapr_tce_create struct has 4x32bit and 2x64bit fields
which should have resulted in sizeof(fio_iommu_spapr_tce_create) equal
to 32 bytes. However due to the gcc's default alignment, the actual
size of this struct is 40 bytes.
This fills gaps with __resv1/2 fields.
This should not cause any change in behavior.
