mbind: add BUG_ON(!vma) in new_vma_page()
new_vma_page() is called only by page migration called from do_mbind(),
where pages to be migrated are queued into a pagelist by
queue_pages_range(). queue_pages_range() confirms that a queued page
belongs to some vma, so !vma case is not supposed to be happen. This
patch adds BUG_ON() to catch this unexpected case.
