CHROMIUM: media: virtio: Use stream_id from request for tracing

This patch changes tracing functions to rely on request, rather then on
response. Currently the crosvm's implementation of virtio-video backend
does not passes the stream id in the command response and fixing this is
not required and would be time consuming.
