Subject: selftests/damon/debugfs_duplicate_context_creation: hide errors from expected file write failures

debugfs_duplicate_context_creation.sh does an invalid file write to ensure
it fails. Check of the failure is sufficient, so the error message from
the failure only makes the output unnecessarily noisy. Hide it.
