[PATCH] AP: enable H2E on 6GHz when SAE is used

[Nicolas Escande]

Even if the use of H2E isn't strictly mandatory when using SAE on 6Ghz, WPA3
personnal pushes it on 6GHz.
So lets automatically enable it by setting sae_pwe=2. This will allow both the
hunting-and-pecking and hash-to-element to work (and be backward compatible)
