xinetd init.d Script Can Cause Multiple Instances to Run

The init.d script for xinetd seems to have some issues. If it's started before the upstart script, two instances of xinetd can be running.

Also, the .pid file location in the init.d script is a different location than the upstart script. While more checks should be done in the init.d script to see if an instance is already running, making both .pid files the same would do a lot to help this issue.

Steps to reproduce:

root@pslchi6ddevtest1:/etc/init.d# /etc/init.d/xinetd start
 * Starting internet superserver xinetd [ OK ]
root@pslchi6ddevtest1:/etc/init.d# service xinetd start
xinetd start/running, process 11941
root@pslchi6ddevtest1:/etc/init.d# ps -ef |grep xinet
root 11933 1 0 13:58 ? 00:00:00 /usr/sbin/xinetd -pidfile /run/xinetd.pid -stayalive -inetd_compat -inetd_ipv6
root 11941 1 0 13:58 ? 00:00:00 /usr/sbin/xinetd -dontfork -pidfile /var/run/xinetd.pid -stayalive -inetd_compat -inetd_ipv6
