iommu: io-pgtable-arm: Correctly update *size in map_sg
Currently, in the arm_lpae_map_sg early return path (when neither READ
nor WRITE permissions were specified), we don't store the "partially
mapped" size in the size output parameter, as is expected. This could
result in someone up the stack using an uninitialized variable. Fix
this by storing 0 in *size when there's nothing to do.
