tunnels: add __rcu annotations
Add __rcu annotations to :
(struct ip_tunnel)->prl
(struct ip_tunnel_prl_entry)->next
(struct xfrm_tunnel)->next
struct xfrm_tunnel *tunnel4_handlers
struct xfrm_tunnel *tunnel64_handlers
And use appropriate rcu primitives to reduce sparse warnings if
CONFIG_SPARSE_RCU_POINTER=y
