With systemd, you need to 'systemctl mask NetworkManager' and then 'systemctl stop NetworkManager' to prevent it from being D-Bus activated too. The reason I say this is because in your logs there are locally-generated disconnections, and that happens when NetworkManager is still running and hasn't been told to stop handling WiFi, and then somebody runs another wpa_supplicant alongside.
