[PATCH 17/19] VFS: use sb_is_dirty helper

[Artem Bityutskiy <Artem.Bityutskiy@nokia.com>]

From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
Subject: [PATCH] VFS: use sb_is_dirty helper

... instead of checking 's_dirt' directly. This is just
a little cleaner and more consistent. We have only 3
VFS helpers which access 's_dirt' now.
