This does not look reasonable since it would break backwards
compatibility with existing hostapd SAE configuration and would prevent
updated hostapd from starting with previously working configuration.
Furthermore, this does not update hostapd/hostapd.conf to match. I'll
drop this part about renaming the configuration variable itself.

I'll drop these changes to test_sae.py since they should not be needed
with backwards compatible manner of handling configuration parameter
names.
