[PATCHv5 05/16] AFFS: clean up dirty flag usage

[Artem Bityutskiy <dedekind1@gmail.com>]

From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

In 'affs_write_super()': remove ancient and wrong commented code,
remove unneeded 'clean' variable, so the function becomes a bit
cleaner and simpler.

In 'affs_remount(): remove unnecessary SB dirty flag changes.
