When CONFIG_HUGETLBFS is not set, there are two problems. One
is implicit declaration of function get_hwpoison_hugetlb_folio(),
the other is get_hwpoison_huge_page() is defined but not used.
Fix them all by defining get_hwpoison_hugetlb_folio() instead of
get_hwpoison_huge_page() when !CONFIG_HUGETLB_PAGE.
Fixes: 92e109a2c5a7 ("mm/hugetlb: convert get_hwpoison_huge_page() to folios")

I believe this issue has been fixed by this patch:
https://lore.kernel.org/linux-mm/20230119111920.635260-1-arnd@xxxxxxxxxx/T/
which has been added to mm-unstable now.
Thanks,
