missing parameter to status in upstart pre-stop script which is not needed regardless

In the provided upstart configuration file /etc/init/xinetd.conf, there is the pre-stop script

pre-stop script
  xinetd_pid=$(status | awk '/stop\/pre-stop/ { print $NF }')
  [ -n "${xinetd_pid}" ] || exit 0
  kill -QUIT "${xinetd_pid}"
end script

The status command as written will always echo the message

status: missing job name
Try `status --help' for more information.

which will go to stderr and so the variable xinetd_pid will always be blank.

This is because the jobname parameter has been omitted from the status command and thus the xinetd process is never killed.

Therefore the line should read

 xinetd_pid=$(status xinetd | awk '/stop\/pre-stop/ { print $NF }')

However because xinetd is running in non-daemon mode, upstart knows the pid of the running xinetd so successfully kills it.

Therefore the pre-stop script which is broken is not needed regardless and after removing the pre-stop script and testing with
start, stop, status and checking with ps, the xinetd process is successfully stopped and started, demonstrating that this snippet
should be removed because it is broken and pointless.
