mm,hugetlb: drop clearing of flag from prep_new_huge_page
Pages allocated via the page allocator or CMA get its private field cleared by means of post_alloc_hook(). Pages allocated during boot, that is directly from the memblock allocator, get cleared by paging_init()-> .. ->memmap_init_zone-> .. ->__init_single_page() before any memblock allocation. Based on this ground, let us remove the clearing of the flag from prep_new_huge_page() as it is not needed. This was a leftover from commit 6c037149 ("hugetlb: convert PageHugeFreed to HPageFreed flag"). Previously the explicit clearing was necessary because compound allocations do not get this initialization (see prep_compound_page).
