Not using pxIndex to iterate ready list in trace utility (#1000)

Browse Source 
* pxIndex should only be used when selecting next task. Altering pxIndex
  of a ready list will cause the scheduler to be unable to select the
  right task to run. Using a for loop if traversing the list for trace
  utility is required.
* Not defining listGET_OWNER_OF_NEXT_ENTRY when using SMP scheduler
