Problem - The failure on PB2 is possbily due to the port number being still in
          use even after the server restarts which is not reflected in the
          server restart.
      
Fix - The problem is fixed by starting the servers forcefully using the option
      file and also the parameters for the server restart is passed correctly.

mysql-test/suite/rpl/t/rpl_report_port-master.opt:
  Option file for the master.
