Quick follow-up - I suspected the issue may be with wpa_supplicant rather than udev / kernel config.
Since this does connect properly on open wireless networks the issue is now only with WPA/WPA2. It seems even the latest dev builds of Ubuntu are still stuck using wpa_supplicant 2.4.x rather than hopping over to 2.5 which I believe contains a fix needed for the libertas chipset to properly authenticate with WPA/WPA2 networks. I therefore decided to compile version 2.5 of wpa_supplicant myself and install it on a Ubuntu 16.04.1 clean install - looks like that actually fixed the problem. So the end result is - the ubuntu 2.4 wpa_supplicant doesn’t work with libertas+libertas_sdio but it *does* work properly with wpa_supplicant 2.5.
