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.
