History
Jouni Malinen f214361581 SAE: Reuse previously generated PWE on a retry with the same STA 
Do not start SAE authentication from scratch if a STA starts a new
attempt for the same group while we still have previously generated PWE
available. Instead, use the previously generated PWE as-is and skip
anti-clogging token exchange since the heavy processing is already
completed. This saves unnecessary processing on the AP side in case the
STA failed to complete authentication on the first attempt (e.g., due to
heavy SAE load on the AP causing a timeout) and makes it more likely for
a valid STA to be able to complete SAE authentication during a DoS
attack.
