better patch for audioresample drift

Attaching a better patch, which doesn't have stray g_prints, but fixes the bug
more nicely - the actual problem was that the existing rounding code for in
transform_size could calculate buffer sizes that don't contain a complete frame
of samples because it didn't include the channel count in its calculations.

For example, when going 48khz->44.1khz with stereo 32bit samples, it would
calculate that 9216 input bytes yields 8468 output bytes, which is 1058.5
output samples.
