Second set of fixes for v5.17. This is the first pull request with
both driver and stack patches.
Most important here are a regression fix for brcmfmac USB devices and
an iwlwifi fix for use after free when the firmware was missing. We
have new maintainers for ath9k and wcn36xx as well as ath6kl is now
orphaned. Also smaller fixes to iwlwifi and stack.
