[Pacemaker] Can't failover Master/Slave with group(primitive x3) setting

[Junko IKEDA]

Hi,

Pacemaker 1.1 shows the same behavior.
It seems that the following chengeset has the problems.

http://hg.clusterlabs.org/pacemaker/stable-1.0/diff/281c8c03a8c2/pengine/native.c

I could get the expected behavior with the latest Pacemaker 1.0 after
reverting the above change.

Thanks,
Junko
