Cleanup leaking goroutine

Cleanup potential go-routine leak in ExecSync path by removing timeout support. Timeout support is added in https://github.com/kubernetes/kubernetes/pull/33366 and https://github.com/kubernetes/kubernetes/pull/35893, and until those merge this is consistent with current behavior.
