Couple of fixes: 

- ath12k performance regression from -rc1
  - cfg80211 counted_by() removal for scan request
    as it doesn't match usage and keeps complaining
  - iwlwifi crash with certain older devices
  - iwlwifi missing an error path unlock
  - iwlwifi compatibility with certain BIOS updates
