qcam: Don't crash if camera can't be opened
If the camera specified on the command line can't be opened, the MainWindow constructor still proceeds to check the startStopAction_, which results in MainWindow::startCapture() being called and trying to use a null camera_ object. Fix this by returning from the constructor as soon as the error is detected. This also fixes a similar crash if the camera selection dialog box is closed without selecting a camera.
