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. :-) Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
