fix swr_convert buffering of packed audio
...
swr_convert is not properly buffering packed input audio when the
output is not large enough, and when resampling is not actually needed
(same samplerate and no SWR_FLAG_RESAMPLE).
buf_set() is only handling the first channel and leaving the others as-is.
Sample program to reproduce the problem is here https://gist.github.com/2431768
