Revert second repo-setup run for overcloud nodes

This commit reverts the workaround that was the second run of repo-setup
on overcloud noeds. This workaround was a short-term fix to allow stable
releases to use CI, however a better fix has been created involving the
refactoring of the vxlan networking code that is dependent on this
patch.
