Pablo Neira Ayuso 0165d9325d netfilter: nf_tables: fix racy rule deletion 
We may lost race if we flush the rule-set (which happens asynchronously
via call_rcu) and we try to remove the table (that userspace assumes
to be empty).

Fix this by recovering synchronous rule and chain deletion. This was
introduced time ago before we had no batch support, and synchronous
rule deletion performance was not good. Now that we have the batch
support, we can just postpone the purge of old rule in a second step
in the commit phase. All object deletions are synchronous after this
patch.

As a side effect, we save memory as we don't need rcu_head per rule
anymore.
