Re: [PATCH] ipv6: Prevent access to uninitialized fib_table_hash via /proc/net/ipv6_route

We will now initialize fib6_init() before ip6_net_route_net_ops is registerd.

This causes fib6_net_init() to run before net->ipv6.ip6_null_entry it
initialized.

Any route lookup will crash when we dereference a root's ->leaf
because it will be NULL.

I've decided to revert this change for now.
