[PATCH 6/8] sink, source: Return early from pa_*_update_rate(), if nothing needs to be done

[tanu.kaskinen@xxxxxxxxxxxxxxx (Tanu Kaskinen)]

A later patch depends on this to avoid pa_source_update_rate() from
being run recursively (it will be called twice, but thanks to this
change, the second call will be a no-op).
