    CentOS: Fix no else section defined in the inline if-expression

    The else section was not defined in the inline if-expression in
    "Write required system controller keystone user and project Ids
    to static hieradata if it's subcloud" task in the
    apply_bootstrap_manifest ansible playbook for CentOS.

    This error was caused by the previous code merge of
    "Debian: Fix openstack secret get failure"
    (https://review.opendev.org/c/starlingx/ansible-playbooks/+/856299).

    Test Plan:
    PASS: Successfully run bootstrap of subcloud on CentOS.
