If a control has an invalid default value then we might fail to set it
when restoring the default value after our write tests, for example due to
correctly implemented range checks in put() operations. Currently this
causes us to report the tests we were running as failed even when the
operation we were trying to test is successful, making it look like there
are problems where none really exist. Stop doing this, only reporting any
issues during the actual test.
We already have validation for the initial readback being in spec and for
writing the default value back so failed tests will be reported for these
controls, and we log an error on the operation that failed when we write so
there will be a diagnostic warning the user that there is a problem.
