cdr.c: Defer getting ao2_global_obj_ref() until needed.
The CDR performance gets worse the further it gets behind in processing
stasis messages. One of the reasons is we were getting the global config
even if we didn't need it.
* Most uses of the global config were only needed on off nominal code
paths so it makes sense to not get it until absolutely needed.
