xfrm: add rcu_access_pointer to silence sparse warning for xfrm_input_afinfo

xfrm_input_afinfo is __rcu, we should use rcu_access_pointer to avoid
a sparse warning:
net/xfrm/xfrm_input.c:78:21: error: incompatible types in comparison expression (different address spaces):
net/xfrm/xfrm_input.c:78:21:    struct xfrm_input_afinfo const [noderef] __rcu *
net/xfrm/xfrm_input.c:78:21:    struct xfrm_input_afinfo const *
