2b1d3f8fbd188d84713d25e9d1c3126e3852a1b3 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.
