check: don't leave the scratch filesystem mounted after _notrun

Unmount the scratch filesystem if a test decides to _notrun itself
because _try_wipe_scratch_devs will not be able to wipe the scratch
device prior to the next test run.  We don't want to let scratch state
from one test leak into subsequent tests if we can help it.
