Have you tried this with WPA (which would disable PMKSA caching)?

It looks like the driver is able to associate with the AP, but no EAPOL
frames are delivered to wpa_supplicant. This would requiring debugging
the driver and/or the AP. A good starting step would be to use a
wireless sniffer to capture the frames sent between the devices and see
where the AP is sending out EAPOL-Key messages after association.
