Lumpy reclaim worked with two passes - the first which queued pages for
IO and the second which waited on writeback. As direct reclaim can no
longer write pages there is some dead code. This patch removes it but
direct reclaim will continue to wait on pages under writeback while in
synchronous reclaim mode.
