Subject: [PATCH] [config-setup]: Fix a bug in checking if updategraph is
 enabled (#7093)

Encounter error during "config-setup boot" if the updategraph is enabled.

How I did it
Correct the code inside the config-setup script.
Remove the space between the assignment operator.

How to verify it
Remove the /etc/sonic/config_db.json and reboot the device.
Originally, it will return following error after boot up.
rv: command not found
After modification, it can correctly parse the status of updategraph without error.
