message:
  Fix incorrect PSI_stage_info message, found during MDEV-6676 development.
  
  Marked-for: 10.0
  
  In parallel replication, threads can do two different waits for a prior
  transaction. One is for the prior transaction to start commit, the other is
  for it to complete commit.
  
  It turns out that the same PSI_stage_info message was errorneously used in
  both cases (probably a merge error), causing SHOW PROCESSLIST to be
  misleading.
  
  Fix by using correct, distinct message in each case.
