logging: fix oedebug loglevel test

When the existing test for loglevel fails, the syntax used results in the recipe
exiting with a silent failure. Performing any bash command after the test block
resolves the problem, such as "shift" or "echo ''". Rewriting with 'if []; then'
blocks provides a cleaner syntax and also resolves the failure.
