IPv6: add "disable" module parameter support to ipv6.ko
Add "disable" module parameter support to ipv6.ko by specifying
"disable=1" on module load. We just do the minimum of initializing
inetsw6[] so calls from other modules to inet6_register_protosw()
won't OOPs, then bail out. No IPv6 addresses or sockets can be
created as a result, and a reboot is required to enable IPv6.
