GStreamer camerabin: return the proper camera source

 - return m_cameraSrc for function cameraSource() instead of m_videoSrc.
   m_videoSrc is not always assigned(default 0), it will crash on:
   if (g_object_class_find_property(
      G_OBJECT_GET_CLASS(m_session->cameraSource()), "exposure-mode")) {
   And as the function name says, it would be better to return the
   value m_cameraSrc.
 - make sure pointers are not NULL before using them.
