mm/memblock.c: make the index explicit argument of for_each_memblock_type
for_each_memblock_type macro function relies on idx variable defined in the caller context. Silent macro arguments are almost always wrong thing to do. They make code harder to read and easier to get wrong. Let's use an explicit iterator parameter for for_each_memblock_type and make the code more obious. This patch is a mere cleanup and it shouldn't introduce any functional change.
