Fix bug rook-ceph provision with multi osd on one host

Test case:
1, deploy simplex system
2, apply rook-ceph with below override value
value.yaml
cluster:
  storage:
    nodes:
    - name: controller-0
      devices:
      - name: sdb
      - name: sdc
3, reboot

Without this fix, only osd pod could launch successfully after boot
as vg start with ceph could not correctly add in sysinv-database
