[PATCH 5.18 1080/1095] raw: fix a typo in raw_icmp_error()

[Greg Kroah-Hartman]

From: Eric Dumazet <edumazet@xxxxxxxxxx>

commit 97a4d46b1516250d640c1ae0c9e7129d160d6a1c upstream.

I accidentally broke IPv4 traceroute, by swapping iph->saddr
and iph->daddr.

Probably because raw_icmp_error() and raw_v4_input()
use different order for iph->saddr and iph->daddr.

Fixes: ba44f8182ec2 ("raw: use more conventional iterators")
