net: Convert cfg80211_pernet_ops
This patch finishes converting pernet_operations registered in net/wireless directory. These pernet_operations have only exit method, which moves devices to init_net. This action is not pernet_operations-specific, and function cfg80211_switch_netns() may be called all time during the system life. All necessary protection against concurrent cfg80211_pernet_exit() is made by rtnl_lock(). So, cfg80211_pernet_ops is able to be marked as async.
