completions/nmcli: Exit if networkmanager isn't running

Browse Source 
These printed an error on load if networkmanager isn't running.

Since at that point it's not useful to complete anything, just try the
first call and if that fails exit.

(cherry picked from commit b6f47f76f00ecf2b019de7fd91aa5b8a698679d5)
