Fix stale data in openshift_facts for logging

Currently, some stale facts may be present in
'/etc/ansible/facts.d/openshift.fact' which causes
openshift_facts to fail.

This commit ensures that the data for the 'logging' key
in that file is a dictionary; otherwise we re-initialize
a new dictionary.
