The internal buffers between the CIO2 and ImgU are freed by the CIO2Device::stop() method, which is called first when stopping streaming. The ImgUDevice::stop() method is then called, and attempts to report completion for all queued buffers, which we have just freed. The use-after-free corrupts memory, leading to crashes. Fix this by moving the vector of internal buffers to the IPU3CameraData where it belongs, and free the buffers after stopping both devices.
