muxdemux: Properly assign processing function during mux_prepare() call. 

Currently, after pipeline params propagation, mux/demux processing
function might not be properly set up, if current params mismatch
ones assigned with binary blob during instantiation.
Similar assignment was there originally, but was lost to the history.
