[PATCH] mm: place page->pmd_huge_pte to right union

["Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>]

I don't know what went wrong, mis-merge or something, but ->pmd_huge_pte
placed in wrong union within struct page.

In original patch[1] it's placed to union with ->lru and ->slab, but in
commit e009bb30c8df it's in union with ->index and ->freelist.

That union seems also unused for pages with table tables and safe to
re-use, but it's not what I've tested.

Let's move it to original place. It fixes indentation at least. :)
