Wrong callout of killproc in init.d script

For systems with multiple Jenkins services on one physical server, init script performs "Stop" and "Restart" on first started Jenkins service. 

Repair is very simple.

In default Jenkins  init.d script "stop" function should be edited.

From

stop)
 echo -n "Shutting down Jenkins "
 killproc jenkins
 rm -f $JENKINS_LOCKFILE
 RETVAL=$?
 echo
 ;;

To

stop)
 echo -n "Shutting down Jenkins "
 killproc -p $JENKINS_PID_FILE
 rm -f $JENKINS_LOCKFILE
 RETVAL=$?
 echo
 ;;
