nl80211: Avoid AP mode BUG_ON hang with invalid lock assert
"cfg80211: add assert_cfg80211_lock() to ensure proper protection" added assert_cfg80211_lock() calls into various places. At least one of them, nl80211_send_wiphy(), should not have been there. That triggers the BUG_ON in assert_cfg80211_lock() and pretty much kills the kernel whenever someone runs hostapd.. Remove that call and make assert_cfg80211_lock() use WARN_ON instead of BUG_ON to be a bit more friendly to users.
