If the application was streaming from both videoX and vbiX, and streaming from videoX was stopped, then the vbi streaming also stopped.The cause being that stop_streaming for video stopped the subdevs as well, instead of only doing that if dev->streaming_users reached 0. au0828_stop_vbi_streaming was also wrong since it didn't stop the subdevs at all when dev->streaming_users reached 0.
