Why engine-setup is failing while checking "Global Maintenance" even when the HE environment is in Maintenance mode

Issue

• Below error is logged while running # engine-setup on RHV-Manager:

[ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data

• hosted-engine --vm-status shows the HE environment in global maintenance mode.
