ceph-disk: remove unused methods

this is a follow-up of aac89719881c2788941b74d385d95860e520ea78, which
replaced partx with partprobe. and we don't need to detect the platform
to decide if we need to use partx or not anymore with that commit
because we are dropping the support of distros w/o partprobe.
