kubeadm: Don't dump backtrace on reset

The current code logs an error and full blown backtrace if we fail to remove the containers upon reset. This creates unneeded, huge and rather scary log message. Fix that by leaving just the error message. Signed-off-by: Rostislav M. Georgiev <rostislavg@vmware.com>
