iommu: change iommu_map_sgtable to return signed values

Browse Source 
The iommu_map_sgtable() function returns ssize_t and negative error
codes but it's declared as size_t instead.  I think that static checkers
would have complained if this caused a bug, but even though it doesn't
cause a bug, it's definitely worth fixing.
