[PATCH] mm/hugetlb_vmemmap: update outdated comment

[kexinsun]

The function vmemmap_pte_range() was refactored into vmemmap_pte_entry()
by commit fb93ed63345f ("mm: hugetlb_vmemmap: use walk_page_range_novma()
to simplify the code"). Both functions share the key behavior that the
reuse page is identified first before remapping begins. Update the
comment accordingly.
