netfilter: nf_log: wait for rcu grace after logger unregistration
[ Upstream commit ad5001cc7cdf9aaee5eb213fdee657e4a3c94776 ]
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")
