Kuniyuki Iwashima 76ea2ba229 ip6mr: Convert ip6mr_rtm_getroute() to RCU. 
ip6mr_rtm_getroute() calls __ip6mr_get_table(), ip6mr_cache_find(),
and ip6mr_fill_mroute().

Once created, struct mr_table is not freed until netns dismantle,
so it's safe under RCU.

ip6mr_cache_find() iterates mrt->mfc_hash with rhl_for_each_entry_rcu().
struct mr_mfc is freed with call_rcu(), so this is also safe under
RCU.

ip6mr_fill_mroute() calls mr_fill_mroute(), which properly uses
RCU helpers.

Let's call them under RCU and register ip6mr_rtm_getroute() with
RTNL_FLAG_DOIT_UNLOCKED.
