cfg80211: Add an attribute to set inactivity timeout in AP mode
This patch adds an attribute, NL80211_ATTR_INACTIVITY_TIMEOUT, to set the inactivity timeout which can be used to remove the station in AP mode. This can be passed in NL80211_CMD_START_AP and used by the drivers which have AP MLME in firmware but don't support get_station() properly. To disable inactivity timer in userspace, wpa_s for example, there is a new flag, NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags through which drivers can register their capability to use the inactivity timeout to free the stations.
