Remove print in test

[khanhtc1202]

What type of PR is this?

/kind failing-test

What this PR does / why we need it:

This fmt.Print causes an unexpected line in stdout for test run output JSON, which causes an error for future possible go test tools. And we don't use it anyway, so I think it's better to remove it.
