Hugh Dickins d71f830d8c mm: fix the NULL mapping case in __isolate_lru_page() ...

commit 145e1a71e0 upstream.

George Boole would have noticed a slight error in 4.16 commit
69d763fc6d ("mm: pin address_space before dereferencing it while
isolating an LRU page").  Fix it, to match both the comment above it,
and the original behaviour.

Although anonymous pages are not marked PageDirty at first, we have an
old habit of calling SetPageDirty when a page is removed from swap
cache: so there's a category of ex-swap pages that are easily
migratable, but were inadvertently excluded from compaction's async
migration in 4.16.
