Can no longer build ipv6 built-in (2.6.11, today's BK head)

Changeset
herbert@gondor.apana.org.au|ChangeSet|20050310043957|06845
added cleanup to ipv6_init(), which calls ip6_route_cleanup()

ip6_route_cleanup() is marked __exit so cannot be called from an
__init section -- it's discarded by the linker from the image
(although it'll be retained in a module).

You get errors like this:
ip6_route_cleanup: discarded in section `.exit.text' from
net/built-in.o
xfrm6_fini: discarded in section `.exit.text' from net/built-in.o
fib6_gc_cleanup: discarded in section `.exit.text' from net/built-in.o
ipv6_packet_cleanup: discarded in section `.exit.text' from
net/built-in.o

A simple fix is to delete the __exit from the various functions now that
they're called other than at module_exit.
