Fix golint errors

[vrothberg]

I wanted to enable golangci-lint for the test/ directory (which is currently not checked) and noticed that new errors were introduced to the rest of the code. I have no idea how that was possible but now the linter is happy again.

@giuseppe @mheon @baude @TomSweeneyRedHat @rhatdan PTAL

Note that this PR is not enabling the linter for ./test. Something we can tackle later.

LGTM, but gating is angry

Should be happy now. Had some whitespaces in the commits :^)

Did we turn off branch protection? I have merge permission even though the PR isn't green yet

LGTM assuming happy tests

I assume these are flakes (for the record):

I seem to be unable to restart the flaked test. Maybe someone else can try?

[vrothberg]

Seems like an UI issue here. Jobs are running but the UI isn't updating. @cevich is investigating.
