[PATCH 5.4 334/340] xfrm: interface: use icmp_ndo_send helper

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <ja...@zx2c4.com>

commit 45942ba890e6f35232727a5fa33d732681f4eb9f upstream.

Because xfrmi is calling icmp from network device context, it should use
the ndo helper so that the rate limiting applies correctly.
