CSA broken with !use_chanctx drivers?

Hi Michal, Johannes and I were checking the channel switch code (namely to see if implementing the drv_channel_switch op was fine in our case) and we saw that CSA with non-chanctx drivers seems to be broken. In commit 4c3ebc56 (mac80211: use chanctx reservation for STA CSA) we lost this piece of
