driver: wifi: esp32: fix send data for AP_STA mode

Fixes the check for connected interface if CONFIG_ESP32_WIFI_AP_STA_MODE=y
(different data objects for STA (esp32_data) and AP (esp32_ap_sta_data)).
As the correct data object is linked to device object, we can check for
ESP32_STA_CONNECTED or ESP32_AP_CONNECTED in dev->data.
This fixes AP mode in samples/net/wifi/apsta_mode if STA WIFI_SSID/WIFI_PSK
are invalid and no STA connection can be established before
(samples/net/wifi/apsta_mode/src/main.c#L28-L29) for all ESP32 derivates.

Fixes false check from 183b74c
