Revert commit e02e290d7c

Using the latest stable-3.x branch, clients hang for a while, and e.g. paplay
times out with the error "Failed to drain stream: Timeout". Other clients like
mplayer seem to be stuck indefinitely.

I bisected it to commit e02e290d7cccd0cfbc89bacf5c0be7934ee58ece (Call
change_cb() only when there's an actual change.). With this reverted it works
again. (see attachment)

In the case of paplay it seems to be stuck in the ppoll call from
pulse/mainloop.c:862 until it times out and then exits with an error.</pre>
