ipv6: route: enforce RCU protection in rt6_update_exception_stamp_rt()

We must access rt6_info->from under RCU read lock: move the
dereference under such lock, with proper annotation.

v1 -> v2:
 - avoid using multiple, racy, fetch operations for rt->from

Fixes: a68886a69180 ("net/ipv6: Make from in rt6_info rcu protected")
