rtl8189fs: Fix p2p-go advertising

[Azq2]

I'm trying to use WiFi P2P group owner on this driver, but my p2p access point looks like regular access point and not listed in "WiFi Direct" list on Android phone.

Main reason of this problem - "p2p ie" from wpa_supplicant not passed into wifi beacon

I found other driver where p2p_go works fine (but for other chip) https://github.com/aircrack-ng/rtl8812au

And I make diff of os_dep/linux/ioctl_cfg80211.c

 	ret = rtw_add_beacon(adapter, settings->beacon.head, settings->beacon.head_len,
 		settings->beacon.tail, settings->beacon.tail_len);
 
+        // In cases like WPS, the proberesp and assocresp IEs vary from the beacon, and need to be explicitly set
+        if(ret == 0) {
+                if(settings->beacon.proberesp_ies && settings->beacon.proberesp_ies_len > 0) {
+                        rtw_cfg80211_set_mgnt_wpsp2pie(ndev, (char *)settings->beacon.proberesp_ies,
+                                settings->beacon.proberesp_ies_len, 0x2/*PROBE_RESP*/);
+                }

+                }
+        }
+
+	adapter->mlmeextpriv.mlmext_info.hidden_ssid_mode = settings->hidden_ssid;

 	if (settings->ssid && settings->ssid_len) {
 		WLAN_BSSID_EX *pbss_network = &adapter->mlmepriv.cur_network.network;
 		WLAN_BSSID_EX *pbss_network_ext = &adapter->mlmeextpriv.mlmext_info.network;

 }

And after backporting of this changes p2p_go now works fine!
Now I see my orangepi on my android device in "Wi-Fi Direct" list.

Hello @Azq2, when I apply this diff file, I cannot see my board on Android phone.
