Remove unreachable error handling paths

[saschagrunert]

The only error the Registrar can return within the Reserve() function is registrar.ErrNameReserved. This means the lines 620 and 642 in container_server.go were unreachable for now. I also removed the additional Get since the only reason that the reservation fails is that it is already reserved.

Hi @saschagrunert. Thanks for your PR.

I'm waiting for a kubernetes-sigs or 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.
