Fix unreachable code for ipvs test

[AllenZMC]

What type of PR is this?

/kind bug
/kind cleanup

What this PR does / why we need it:

Optimize test cases to prevent errors in one case from affecting other cases.

if len(tc.previousEndpoints) != len(tc.currentEndpoints) {
	t.Fatalf("[%d] different lengths of previous and current endpoints", tci)
	continue
}

continue is unreachable, so if there is an error here, other cases will not be executed.

Which issue(s) this PR fixes:

Hi @AllenZMC. Thanks for your PR.

I'm waiting for a kubernetes 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.
