nl80211: Fix send_mlme for SAE external auth

Browse source 
When external authentication is used, the station send mlme frame (auth)
to the driver may not be able to get the frequency (bss->freq) after
hostap.git commit b6f8b5a9 ("nl80211: Update freq only when CSA
completes"). Use the assoc_freq to send the MLME frame when SAE external
authentication is used to avoid this issue.
