Test steps:
1. Create a VM with 8.2 LVM on-demand image in XXX(VM drive is larger(64G) than the image)
2. Check the root drive (/) is not resized
3. Uninstall old version cloud-utils-growpart-0.29-3.el8 and cloud-init-18.5-12,
   Install cloud-utils-growpart-0.31-1.el8 and cloud-init-19.4-7.el8
4. Clean the VM cloud-init related files/configs, reboot the VM
5. Login the VM, check the root drive (/) is not resized

6. Check the /var/log/cloud-init.log, it reports failed log:
- cc_growpart.py[DEBUG]: '/' SKIPPED: device_part_info(/dev/mapper/rootvg-rootlv) failed: /dev/mapper/rootvg-rootlv not a partition
