Description of problem:
Clone the upstream bug to ocp-3.9 https://github.com/kubernetes/kubernetes/issues/57239
When enable cpumanager by --cpu-manager-policy=static, but not set --kube-reserved and --system-reserved, kubelet will get panic error in log

Version-Release number of selected component (if applicable):
openshift v3.9.0-0.16.0
kubernetes v1.9.0-beta1
etcd 3.2.8

How reproducible:
Always

Steps to Reproduce:
1. Configure cpu-manager without '--kube-reserved and --system-reserved' the restart node service

# cat /etc/origin/node/node-config.yaml
...
kubeletArguments:
...
  feature-gates:
  - CPUManager=true
  cpu-manager-policy:
  - static
  cpu-manager-reconcile-period:
  - 5s

# systemctl restart atomic-openshift-node

2. Check the node log
