The majority of them were totally backwards. Change the logic
so that if DELAYED_SYNC *isn't* in the config, we actually flush to disk
before flagging the file system as clean.
That leaves two calls in the DELAYED_SYNC case. More detailed
analysis is needed to make sure that's what's really needed, or if other
call sites also need a fs_sync() call. This patch is at least "less wrong"
than the code was, but further changes should be another patch.
