ods-control not robust in ensuring process running

Instead of checking a pid file, which seemed to exist despite the ods-enforcerd not running, i changed the script for ods-control to have this instead:

                if [ $? -eq 0 ]; then
                #if [ -r "$enforcer_pid_file" ]; then
                        echo "Enforcer is already running"
                        RETVAL=-1
