IJ33574: MMTRACECTL DOES NOT PASS USER NODECLASS NAME

APAR status

• Closed as program error.

Error description

• When running mmtracectl with a nodeclass, output in
  mmlsconfig doesn't show nodeclass but shows node names
  as if a node class was not passed to command.
  
  example:
  
  /usr/lpp/mmfs/bin/mmtracectl --set --trace-recycle=local
  --trace="all 0 io 1 vnop 2" -N usernodeclass
  
  mmlsconfig will show:
  
  [node1,node2]            <----- doesn't honor node class
  name
  trace all 0 io 1 vnop 2
  traceRecycle local
  
  
  it should show:
  
  [usernodeclass]  <--- nodeclass given to mmtracectl
  trace all 0 io 1 vnop 2
  traceRecycle local
