[patch 10/38][IPV6] ip6_fib - make mindless changes

[Daniel Lezcano <dlezcano@xxxxxxxxxx>]

This patch changes all references to the static global variables
fib6_main_tbl and fib6_local_tbl by a pointer. That provides the
minimal changes to dynamically allocate these tables for the network
namespaces.
