Rubber Band DSP: Fix error checking for output

Browse source 
The samples available function returns a signed integer, so it can
apparently return negative on error, and the DSP was incorrectly casting
this to an unsigned type, and thus attempting to buffer an inordinate
number of samples and crashing.
