netfilter: nf_log: wait for rcu grace after logger unregistration
The nf_log_unregister() function needs to call synchronize_rcu() to make sure that the objects are not dereferenced anymore on module removal. Fixes: 5962815a6a56 ("netfilter: nf_log: use an array of loggers instead of list") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
