rgmanager: Don't exit uncleanly when cman asks us to shut down.
 

Original patch from Lon rediffed to apply to the current tree:

"Previous to this, rgmanager would uncleanly exit if you
issued a 'service cman stop'. This patch makes it uncleanly
exit if 'cman_tool leave force' or a corosync/openais crash
occurs, but in a simple cman_tool leave, rgmanager will no
longer exit uncleanly."

Without this patch, issuing 'service cman stop' when rgmanager
is running will make it impossible to stop the cman service because
rgmanager will have exited without releasing its dlm lockspace.

Resolves: rhbz#769730
