IEEE P802.11be/D4.0 does not seem to have changed the rules for deriving
PTK in FT hierarchy since there were no changes to 12.7.1.6.5 (PTK)
where BSSID and STA-ADDR are used. However, the MLO changes for FT and
for PTK derivation in non-FT cases seem to imply that this FT case is
also supposed to use MLD MAC addresses.
Commit 628b9f1022 ("wlantest: Derive PMK-R1 and PTK using AA/SPA for
MLO FT over-the-DS") did this already for FT over-the-DS, so do the same
for FT over-the-air.

The driver might decide to change the operating band on its own, e.g.,
when trying to use a single channel in AP + AP case. A CSA event will be
notified to hostapd to update the channel/frequency, but hw_mode did not
get updated accordingly.
This may cause hostapd interface restarting to fail, e.g., with control
interface DISABLE / ENABLE commands at configured_fixed_chan_to_freq(),
because of the mismatch between conf->channel and conf->hw_mode.
Update hw_mode right after channel change to fix this.
