Fix order of logging calls in handler startup code

Is this a BUG FIX or a FEATURE ?:

What this PR does / why we need it:
The previous order of these calls resulted in the container exiting
before the log message was output, which made it impossible to debug
what went wrong. This just changes the order so the message is logged
and then the process exits.

Special notes for your reviewer:

Release note:

Fix logging so the handler process won't exit silently in some error situations.

Hi @cybertron. Thanks for your PR.

I'm waiting for a nmstate member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
