esp_wifi: fix clearing default wifi netif procedure

Browse Source 
Prior to this change "esp_wifi_clear_default_wifi_driver_and_handlers"
will not remove netif pointer from table when both AP and STA interfaces were
created and destroying default wifi interfaces is done in unfortunate
order. As a result there is dangling pointer left and it may cause crash in
later code (i.e. when esp_wifi_stop() is called).
