sparc/iommu: fix ->map_sg return value

Just decrementing the sz value will lead to an incorrect return value.
Instead of just introducing a local variable switch to the standard
for_each_sg helper and standard naming of the arguments.

Fixes: 1ed24410be ("sparc: remove the sparc32_dma_ops indirection")
