ipv6: use call_rcu_hurry() in fib6_info_release()
This is a followup of commit c4e86b4363
("net: add two more
call_rcu_hurry()")
fib6_info_destroy_rcu() is calling nexthop_put() or fib6_nh_release()
We must not delay it too much or risk unregister_netdevice/ref_tracker
traces because references to netdev are not released in time.
This should speedup device/netns dismantles when CONFIG_RCU_LAZY=y
