[CentOS] CentOS 6: corosync and pacemaker won't stop (patch)

Hi,

I cannot 'halt' my CentOS 6 servers while running corosync+pacemaker.
I believe the runlevels used to stop corosync and pacemaker are not in the
correct order and create the infinite "Waiting for corosync services to
unload..." loop thing.

This is my first time with this cluster technology but apparently pacemaker
has to be stopped /before/ corosync.
Applying the following patch to pacemaker init script fix this issue.
