From: Darrick J. Wong <djwong@xxxxxxxxxx>
Quite a while ago, I added --duration= arguments to fsx and fsstress,
and apparently I forgot to update the scrub stress loops to use them.
Replace the usage of timeout(1) for the remount_period versions of the
loop to clean up that code; and convert the non-remount loop so that
they don't run over time.
