[Pacemaker] Manual fence confirmation by stonith_admin doesn't work again.

[Nikita Staroverov]

Hello!

Some months ago i wrote about manual fence confirmation by stonith_admin 
-C. Andrew fixed this, but it works only for pacemaker+corosync.
CMAN-based configuration won't do manual fencing this way.
I tried stonith_admin -C , pacemaker made node  clean offline, but 
didn't notify CMAN about this. CMAN's fenced was tried fence_pcmk 
indefinitly.
fence_ack_manual works as expected.
I think pacemaker must notify CMAN about manual fence confirmations.
Tested configuration: CentOS 6.5, pacemaker 1.1.10 from centos repos.
