[IPV6] MCAST: Fix joining all-node multicast group on device initialization.
Join all-node multicast group after assignment of dev->ip6_ptr because it must be assigned when ipv6_dev_mc_inc() is called. This fixes Bug#7817, reported by <gernoth@informatik.uni-erlangen.de>. Closes: 7817 Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
