PDS 0.98p release

PDS 0.98p is released with the following changes

1. Minor code optimization here and there.
2. Balance optimization. This fix regression in 098n when workload % < core number.
3. 32ms balance interval.

This is the last PDS release in 4.16 kernel, thanks for the benchmark testing by Predo and Manuel, a regression in 098n release is identified and fix. In this release, the balance interval also increase to 32ms, this will help with throughput, let's test this setting before there is new way to do balance later(maybe next kernel release).

Enjoy PDS 0.98p for v4.16 kernel, :)
