    netfilter: nfnetlink_log: fix silly refcount leak
    
    Quick fix for memory/module refcount leak.
    Reference count of listener instance never reaches 0.
    
    Start/stop of ulogd2 is enough to trigger this bug!
    
    Now, refcounting there looks very fishy in particular this code:
    
     	if (!try_module_get(THIS_MODULE)) {
    		...
    
    and creation of listener instance with refcount 2,
    so it may very well be ripped and redone.  :-)
