mm/hugetlb: use helper huge_page_order and pages_per_huge_page 

[ Upstream commit c78a7f3639 ]

Since commit a551643895 ("hugetlb: modular state for hugetlb page
size"), we can use huge_page_order to access hstate->order and
pages_per_huge_page to fetch the pages per huge page.  But
gather_bootmem_prealloc() forgot to use it.
