net: sync skb free reasons
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2184073
Did not included commit 071c0fc6fb91 ("net: extend drop reasons for multiple subsystems")
as it would be appropriate to backport it in its own MR, would have not user for now,
and it's not clear to me how trace_kfree_skb deals with non-core free reasons once applied.
