[ Upstream commit c8bedab2d9a1a0daa49ac20f9928a943f7205582 ]
[WHY] Ensure AVI infoframe updates from stream updates are applied to the active stream so OS overrides are not lost.
[HOW] Copy avi_infopacket to stream when valid flag is set. Follow existing infopacket copy pattern and perform a basic validity check before assignment.
