At first, I thought it would be better to add ASSERT(!m_controller), but we
won't be able to add it, because it's possible that the MediaDevicesRequest is
destructed immediately after created without stop() getting called.

 
 Document* MediaDevicesRequest::ownerDocument()
 {
     if (ExecutionContext* context = executionContext()) {
         return toDocument(context);
     }
 
     return 0;
 }
