Subject: [PATCH] mm/hugetlb: fix get_hwpoison_hugetlb_folio() stub

From: Arnd Bergmann <arnd@...db.de>

The folio conversion patch only changed one of the two implementations,
the empty stub one still needs the corresponding change:

mm/memory-failure.c: In function '__get_hwpoison_page':
mm/memory-failure.c:1335:15: error: implicit declaration of function 'get_hwpoison_hugetlb_folio'; did you mean 'get_hwpoison_huge_page'? [-Werror=implicit-function-declaration]
 1335 |         ret = get_hwpoison_hugetlb_folio(folio, &hugetlb, false);
      |               ^~~~~~~~~~~~~~~~~~~~~~~~~~
      |               get_hwpoison_huge_page

Fixes: 92e109a2c5a7 ("mm/hugetlb: convert get_hwpoison_huge_page() to folios")
