…g on Supervisor card (#1771)

What I did
Fixed #8521

How I did it
Before displaying the warning message, call device_info.is_supervisor() function to check if it is supervisor card, don't display the warning message.

How to verify it
Running the image on supervisor card
Execute the CLI "show interfaces status"
No warning should be seen.
