Revert "mm: simplify code of swap.c"

This reverts commit d8505dee1a87b8d41b9c4ee1325cd72258226fbc.

Chris Mason ended up chasing down some page allocation errors and pages
stuck waiting on the IO scheduler, and was able to narrow it down to two
commits: commit 744ed1442757 ("mm: batch activate_page() to reduce lock
contention") and d8505dee1a87 ("mm: simplify code of swap.c").

This reverts the second one.
