mm: rename __mlock_vma_pages_range() to populate_vma_page_range()
__mlock_vma_pages_range() doesn't necessarily mlock pages. It depends on
vma flags. The same codepath is used for MAP_POPULATE.
Let's rename __mlock_vma_pages_range() to populate_vma_page_range().
This patch also drops mlock_vma_pages_range() references from
documentation. It has gone in cea10a19b797 ("mm: directly use
__mlock_vma_pages_range() in find_extend_vma()").
