Revert "f2fs: fix to set flush_merge opt and show noflush_merge"

This reverts commit 6ba0594a81 which is
commit 967eaad1fe upstream.

Something is currently broken in the f2fs code, Guenter has reported
boot problems with it for a few releases now, so revert the most recent
f2fs changes in the hope to get this back to a working filesystem.
