The machines.raw file is only created if the 'machinectl set-limit'
command returns non-zero exit code. However, this file is expected to
be present later on so we need to make sure that we create without
taking the 'machinectl' exit code into consideration.
Fixes the following problem:
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Device /var/lib/machines.raw not found."}
Depends-On: https://review.openstack.org/#/c/574382/
