Missing running check on init script

Bug description:
Hi, this is the relevant version information:
# lsb_release -rd
Description: Ubuntu 12.04 LTS
Release: 12.04
dpkg -l haproxy|tail -1
ii haproxy 1.4.18-0ubuntu1
fast and reliable load balancing reverse proxy
When I issue a stop to haproxy via the init script, on line 49 it tries to
kill the process and returns 4 in case of failure, which then after iis the
exit status of the script itself.
There are many reasons why stopping a process may fail, one of them is that
the process wasn't actually running. In that case, I think the exit status of
stop should be 0, since the process is stopped.
This caused problems in the following scenario: haproxy governed by
pacemaker if the haproxy process stops abruptly for some reason (crash,
oom-killer), pacemaker will try to stop and start it again, but it will fail to
stop (exit 4, expected 0).
To work around this, I added a check on the init script to see if the process
was running, see patch attached.
