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.
