mm, hugetlb: mark some bootstrap functions as __init
Both prep_compound_huge_page() and prep_compound_gigantic_page() are only called at bootstrap and can be marked as __init. The __SetPageTail(page) in prep_compound_gigantic_page() happening before page->first_page is initialized is not concerning since this is bootstrap.
