Some tests deliberately corrupt scratch devices and so will fail the post-test check. Add a "_require_scratch_nocheck" helper function for such tests to avoid false test failure detection. Also, ensure that _notrun cleans up the trigger for the post-test checks. Otherwise the next test to run may try to validate the scratch/test devices even though they are not used by the test. Further, _check_xfs_filesystem() causes check to exit if it finds a corruption. This is extremely annoying as it terminates the entire test run rather than just reporting that the test fails. Hence add an "iam != check" test before exiting so that calls from tests will cause the test to fail, but calls from check won't cause the harness to exit. There are still some tests that fail the scratch check, these are not obvious test failures and so need further investigation to determine the cause of the failures.
