config: dmesg.sh: Ignore missing handler errors in baseline tests

Ignore "No irq handler for vector" errors in baseline tests [1]. These
errors are harmless. But because of these errors the baseline test gets
marked as failed which makes results dirty. It would have been better to
ignore these errors as known errors on the dashboard. But as we don't
have the functionality at this time. We have decided to ignore these
during the test until we have the functionality.
