swr: move compensation_distance handling to swri_resample caller.
I think there's an off-by-one in terms of the switchpoint where we
switch from dst_incr to ideal_dst_incr, I don't think that's a massive
issue, but just be aware of that. It's probably trivial to prevent but
I don't care.

I could not reproduce any off by 1 error, results are bit exact (michael)
