This reverts commit d3ad2c17b4047
("netfilter: core: batch nf_unregister_net_hooks synchronize_net calls").
Nothing wrong with it. However, followup patch will delay freeing of hooks
with call_rcu, so all synchronize_net() calls become obsolete and there
is no need anymore for this batching.
This revert causes a temporary performance degradation when destroying
network namespace, but its resolved with the upcoming call_rcu conversion.
