Gaurav Batra 1f7aacc5eb powerpc/iommu: Incorrect DDW Table is referenced for SR-IOV device 
For an SR-IOV device, while enabling DDW, a new table is created and
added at index 1 in the group. In the below 2 scenarios, the table is
incorrectly referenced at index 0 (which is where the table is for
default DMA window).

1. When adding DDW

   This issue is exposed with "slub_debug". Error thrown out from
   dma_iommu_dma_supported()

   Warning: IOMMU offset too big for device mask
   mask: 0xffffffff, table offset: 0x800000000000000

2. During Dynamic removal of the PCI device.

   Error is from iommu_tce_table_put() since a NULL table pointer is
   passed in.

Fixes: 381ceda88c ("powerpc/pseries/iommu: Make use of DDW for indirect mapping")
