net: Convert broute_net_ops, frame_filter_net_ops and frame_nat_net_ops
These pernet_operations use ebt_register_table() and ebt_unregister_table() to act on the tables, which are used as argument in ebt_do_table(), called from ebtables hooks. Since there are no net-related bridge packets in-flight, when the init and exit methods are called, these pernet_operations are safe to be executed in parallel with any other.
