mm, hugetlb: increment the number of pages to be reset on HVO
commit 4eeec8c89a0c ("mm: move hugetlb specific things in folio to
page[3]") shifted hugetlb specific stuff, and now mapping overlaps
_hugetlb_cgroup field.
Upon restoring the vmemmap for HVO, only the first two tail pages are
reset, and this causes the check in free_tail_page_prepare() to fail as it
finds an unexpected mapping value in some tails.
Increment the number of pages to be reset to 4 (head + 3 tail pages)
