[ Upstream commit d73b46c3c1 ]
The iommu_table::it_index is a LIOBN which is not initialized on PowerNV
as it is not used except IOMMU debugfs where it is used for a node name.
This initializes it_index witn a unique number to avoid warnings and
have a node for every iommu_table.
This should not cause any behavioral change without CONFIG_IOMMU_DEBUGFS.
