cman: fix data copy and memory leak when reloading config
cman.cluster_id,nodename,two_node information were not copied
from the old to the new config at reload time. This triggers
a problem when <cman is set in cluster.conf and we effectively
drop information from objdb (suboptimal).
Also fix a possible memory leak when we have reload issues.
