Currently |wpa_set_scan_ssids| fully exhausts
|wpa_driver_scan_params.ssid| list when hidden network ID's
are provided via the control interface. This results in us
exceeding the max size for the list advertised by the driver when we add
the "wildcard" scan ssid entry. So, ensure that we leave space for one
more scan ssid entry in the list when we exit out of |wpa_set_scan_ssids|.
