[PATCH 19/35] fs-tests: integck: make operate_on_dir propagate errors up

[Artem Bityutskiy]

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

Make 'operate_on_dir()' functions propogate errors up if any of
the functions it calls failed. This patch also makes 'operate_on_entry()'
return an error code, but without actual implementation.
