igo_nr: compute circular buffer ends in samples not bytes

The processing buffers' end pointers were computed by adding a byte
count to sample-typed pointers, placing the end past the real buffer and
letting the wrap check pass too late. Convert the byte sizes to element
counts when computing the ends.
