BBQ: Recreate BBQ when SurfaceControl changes 1/2
Alternative approach to fab15e55446080bdcfc05ba315e8ef914b0a6f65 which
was racy because the disconnect callback is called without the
BQ lock and the client can continue to modify the BQ state after
disconnecting from the queue.
This approach resets the BQ and BBQ states when the SurfaceControl is
updated. This solves one concrete problem of not relying on the old
SurfaceControl to be destroyed in order to release the currently presented
buffer back to BQ.
In addition this change resets the sync state in BBQ with the rationale
the system does not want to sync on buffers presented on an older
SurfaceControl.
