ipvlan: properly annotate rx_handler access
The rx_handler field is rcu-protected, but I forgot to use the
proper accessor while refactoring netif_is_ipvlan_port(). Such
function only check the rx_handler value, so it is safe, but we need
to properly read rx_handler via rcu_access_pointer() to avoid sparse
warnings.
