1. If firmware supports 4-way handshake offload but not supports DPP
4-way offload, when user first connects encryption network, driver will
set "sup_wpa 1" to firmware, but it will further result in DPP
connection failure since firmware won't send EAPOL frame to host.

2. Fix DPP AP mode handling action frames.

3. For some firmware without fwsup support, the join procedure will be
skipped due to "sup_wpa" iovar returning not-support. Check the fwsup
feature before do such iovar.
