Hotfix: Remove docker ps cmd, wrong condition

The line don't count with pillar docker:host:enabled=False and execute
`docker ps` on hosts where docker was not installed.

This patch fixes customer facing bug, where infrastructure is behind proxy
then we globally define pillar docker:host:proxy, expecting hosts without enabled
docker:host will not interact.
