Johannes Berg e53e9828a8 cfg80211: always free wiphy specific regdomain ... In the (somewhat unlikely) event that we allocate a wiphy, then add a regdomain to it, and then fail registration, we leak the regdomain. Fix this by just always freeing it at the end, in the normal cases we'll free (and NULL) it during wiphy_unregister(). This happened when the wiphy settings were bad, and since they can be controlled by userspace with hwsim, syzbot was able to find this issue.
