mm: remove call to find_vma in pagewalk for non-hugetlbfs
Commit d33b9f45 ("mm: hugetlb: fix hugepage memory leak in
walk_page_range()") introduces a check if a vma is a hugetlbfs one and
later in 5dc37642 ("mm hugetlb: add hugepage support to pagemap") it is
moved under #ifdef CONFIG_HUGETLB_PAGE but a needless find_vma call is
left behind and its result is not used anywhere else in the function.
The side-effect of caching vma for @addr inside walk->mm is neither
utilized in walk_page_range() nor in called functions.
