packet: Kill CONFIG_PACKET_MMAP.
Early on this was an experimental facility that few people other than Alexey Kuznetsov played with. Now it's a pretty fundamental thing and as people add more features to AF_PACKET sockets this config options creates ifdef spaghetti. So kill it off. Signed-off-by: David S. Miller <davem@davemloft.net>
