When brcmf_detach() from the bus layer upon rmmod we can no longer
communicate. Hence we will set the bus state to DOWN and cleanup

deleted before brcmf_cfg80211_detach() because the latter does the
wiphy_unregister() which issues a warning if there are still network
devices linked to the wiphy instance.
