xfs/132 led to XFS shutdown due to the corrupted inode, but it didn't rectify XFS
by umount scratch device.
AFAIK, we don't have to unmount the scratch device when a test
finishes - the test harness is supposed to do that and make sure
that it is in the correct state for the next test to run.

It seems that somewhere along the line this got broken. - I'm
guessing the fact that this test also says "don't check the scratch
device" the test harness is failing to unmount it because it's not
running _check_scratch_device. I'm guessing that it should at least
run _scratch_unmount....
Hi Dave,

Could we just make the test harness call _scratch_unmount after running every test, as below:
