The @nents value that was passed to ib_dma_map_sg() has to be passed
to the matching ib_dma_unmap_sg() call. If ib_dma_map_sg() choses to
concatenate sg entries, it will return a different nents value than
it was passed.
The bug was exposed by recent changes to the AMD IOMMU driver, which
enabled sg entry concatenation.
