Those fields also exists for the dlm_config global variable and get stored in both when setting configfs values. To read values it will always be read out from the dlm_cluster configfs structure but this patch changes it to only use the global dlm_config variable. Storing them in two places makes no sense as both are able to be changed under certain conditions during DLM runtime.
