It looks like it's working to me?  You do get some errors, but I believe
those are harmless and have been suppressed upstream already for a few
years.  You're probably using NM 0.9.8 from Debian?

Anyway, the device enters the "unavailable" state, which means that NM
will manage it, if some conditions are satisfied.  Those include:

a) wpa_supplicant is running
b) the device is not rfkilled

What do you get for the output of:

nmcli dev
nmcli radio
sudo rfkill list
