netfilter: conntrack: expedite rcu in nf_conntrack_cleanup_net_list
nf_conntrack_cleanup_net_list() is calling synchronize_net()
while RTNL is not held. This effectively calls synchronize_rcu().
synchronize_rcu() is much slower than synchronize_rcu_expedited(),
and cleanup_net() is currently single threaded. In many workloads
we want cleanup_net() to be faster, in order to free memory and various
sysfs and procfs entries as fast as possible.
