nl80211: send netdetect configuration info in NL80211_CMD_GET_WOWLAN
Send the netdetect configuration information in the response to NL8021_CMD_GET_WOWLAN commands. This includes the scan interval, SSIDs to match and frequencies to scan. Additionally, add the NL80211_WOWLAN_TRIG_NET_DETECT with NL80211_ATTR_WOWLAN_TRIGGERS_SUPPORTED.
