Description of problem:

Fenced was asking for this from ccsd in order to see if the local node
name was present in the cluster configuration:

    /cluster/clusternodes/clusternode[@name="cyan"]

Unfortunately, because there were no children of that XML node (no
fencing configured), ccsd was crashing.

Version-Release number of selected component (if applicable):
-RHEL4U1 -RHEL4 -RHEL4


How reproducible: 100%

Steps to Reproduce:
1. Create configuration with no fencing specified for a node.
2. Start ccsd on that node.
2. Start fenced on that node.
  
Actual results:
ccsd crashes (SIGSEGV)


Expected results:


Additional info:

This fix is dependent on a fix to ccsd which prevents it from crashing in this case.
