Add changed_when: false to the "get osd ids" statement

The "get osd ids" statement only registers the osd_ids_non_container variable. Running "ls /var/lib/ceph/osd/ | sed 's/.*-//'" should never produce a change on the system. Adding changed_when: false prevents irrelevant change messages from Ansible.
