Summary: portaudio: crash when shutting down callback mode

Initial Comment:
if you select the "portaudio"  audio-backend in "callback" mode and then try to shut it down, Pd will crash, because it calls CloseAudioStreams with the pa_callbackstream, which is not a PABLIO_Stream.

steps to reproduce:
- select "portaudio" as the audio backend
- in the audio-settings that pops-up, enable the "use callbacks" and click on "Apply"
- (this will switch to portaudio/callback)
- now click on "OK" (in the still open settings dialog)
- Pd will segfault (Pd will close portaudio/callback and try to restart it)


the attached patch calls the StopStreaming functions explicitely for the correct stream-type.
