Revert "netfilter: x_tables: Update remaining dereference to RCU"

This reverts commit 443d6e86.

This (and the following) patch basically re-implemented the RCU
mechanisms of patch 78454473

. That patch was replaced because of the
performance problems that it created when replacing tables. Now, we have
the same issue: the call to synchronize_rcu() makes replacing tables
slower by as much as an order of magnitude.

Revert these patches and fix the issue in a different way.
