If do not do it, we will get following issues:
1. Leaving junks after inet6_init failing halfway.
2. Leaving proc and notifier junks after ipv6 modules unloading.

Since NETDEV_REGISTER notifier chain is responsible for creating
inet6_dev{}, we do not need to call ipv6_find_idev() directly here.

- This patch adjusts IPv6 multicast routing module, net/ipv6/ip6mr.c,
to use mroute6 header definitions instead of mroute.
 (MFC6_LINES instead of MFC_LINES, MAXMIFS instead of MAXVIFS, mifi_t
instead of vifi_t.)

- In addition, inclusion of some headers was removed as it is not needed.
