hugetlbfs: use helper macro SZ_1{K,M}
Patch series "A few cleanup and fixup patches for hugetlbfs", v2. This series contains a few cleaup patches to remove unneeded forward declaration, use helper macro and so on. More details can be found in the respective changelogs. This patch (of 5): Use helper macro SZ_1K and SZ_1M to do the size conversion. Minor readability improvement.
