media: au0828: stop video streaming only when last user stops
[ Upstream commit
f604f0f5afb88045944567f604409951b5eb6af8 ]
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.
