This patch corrects how the lparcfg interface was presenting the number of
active and potential processors.  (As reported in LTC bugzilla number 10889).

- Correct output for partition_potential_processors and
  system_active_processors.
- suppress pool related values in scenarios where they do not make
  sense. (non-shared processor configurations)
- Display pool_capacity as a percentage, to match the behavior from
  iSeries code.
