[IPV4/IPV6]: Fix inet{,6} device initialization order.
It is important that we only assign dev->ip{,6}_ptr only after all portions of the inet{,6} are setup. Otherwise we can receive packets before the multicast spinlocks et al. are initialized. Signed-off-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
