common/fuzzy: online re-scrub should not preen

When we're doing the second online scrub (to figure out if the
repair did any good) we shouldn't let that second scrub preen the
filesystem in any way. If scrub finds things it can't/won't preen
that turns into a nonzero return code which gets reported
(incorrectly) as a failure.
