[3/4] xfs: update health status if we get a clean bill of health

Commit Message

If scrub finds that everything is ok with the filesystem, we need a way
to tell the health tracking that it can let go of indirect health flags,
since indirect flags only mean that at some point in the past we lost
some context.
