arch/x86: do not explicitly clear Reserved flag in free_pagetable

In free_pagetable() we use the non-atomic version for clearing the PageReserved bit from the page. free_pagetable() will either call free_reserved_page() or put_page_bootmem(), which will eventually end up calling free_reserved_page(), and in there we already clear the PageReserved flag.
