audioconvert: keep better track of changed params

Browse source 
Keep all the children param flags around and use those to decide
if something changed. Also don't change the param flag serial when
we are simply adding a listener.

This should reduce the number of param updates, most notably the
PropInfo that was updated along with the Props on volume changes.
