raw: fix a typo in raw_icmp_error()

mainline inclusion
from mainline-v6.0-rc1
commit 97a4d46b
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6ECEK
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=97a4d46b1516250d640c1ae0c9e7129d160d6a1c



--------------------------------

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: ba44f818 ("raw: use more conventional iterators")
