QBluetoothDeviceDiscoveryAgent constructor ignores passed QBluetoothAddress on QNX

The following constructor ignores the deviceAdapter parameter:

QBluetoothDeviceDiscoveryAgent(const QBluetoothAddress &deviceAdapter, QObject *parent = 0);

Although QNX only supports one local adapter a class instance should reject a scan with an IOError if the user passes an addres that is not matching the local adapter address.
