Pages allocated after boot 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.
