SAE connection fails if CSA occured during any previous connection
since the start of current wpa_supplicant runtime.
The root cause is as follows. If STA channel changes due to CSA,
then bss->freq is updated in mlme_event_ch_switch. However this
value is not cleared between connections. So later it will be
used during SAE AUTH frame exchange.

By the way, it looks like cleaning up bss->freq field would be a better
option. But so far I could not figure out a good place for this kind of
cleanup. Any suggestions are welcome.
