Description of problem:

Running tests which do hundreds of scale up/downs, the logs get spammed with the following E/Error level message on every scaleup:

E1106 19:17:15.572672   13169 docker_manager.go:357] NetworkPlugin cni failed on the status hook for pod 'cakephp-mysql-example-2-w6j2r' - Unexpected command output Device "eth0" does not exist.

The scale up seems to work ok.  Reduce the loglevel on this message?  or investigate as a real Error?

This is with SELinux disabled and using overlayfs as the docker storage


Version-Release number of selected component (if applicable):   3.4.0.22


How reproducible: Always


Steps to Reproduce:
1.  Install 3.4.0.22 with Docker 1.12.3-3 using overlayfs.  Disable SELinux
2.  oc new-app --template=cakephp-mysql-example and wait for it to build
3.  oc scale --replicas=20 dc/cakephp-mysql-example
4.  Watch syslogs for E messages

Actual results:

11 instances of the above message and a successful scaleup.   Potential underlying issue?

Expected results:

Quiet logs for a successful scaleup.
