mm/hugetlb: fix missing call to restore_reserve_on_error()
When huge_add_to_page_cache() fails, the page is freed directly without
calling restore_reserve_on_error() to restore reserve for newly allocated
pages not in page cache. Fix this by calling restore_reserve_on_error()
when huge_add_to_page_cache fails.
