iommu: Fix trace_map() to report original iova and original size
iommu_map() calls trace_map() with iova and size. trace_map()
should report original iova and original size as opposed to
iova and size after they get changed during mapping. size is
always zero at the end of mapping which is useless to report
and iova as it gets incremented, it is not as useful as the
original iova. Change iommu_map() to call trace_map() to
report original iova and original size.
