[PD] sfplay bugs diff

[Juha Vehviläinen]

Hi,

here's my fix for Winfried Ritsch's "sfplay". The one in ggee seems
to be based on this and is equally buggy, as well as sfread~ (in ggee).

With this fix pd won't crash when playing an 8-channel file, but
it wont play right either, everything is coming from the first few
channels. If you know of a version that works with 8 channels let me know.

Juha
