As raised in #466 it is important in order to avoid unnecessary

The check runs a nmap command from the host running Ansible
to all the ceph nodes with their respective ports.

raw_multi_journal and journal_collocation scenarios separately.
This fails otherwise because whichever var is "first" in the or is most
likely undefined.
