Subject: net: sfc: use skb_list_walk_safe helper for gso segments
Patch-mainline: v5.6-rc1
Git-commit: 69b4ed5cbff54b8279f53a65da111e8d0cc01405
References: jsc#SLE-16683

This is a straight-forward conversion case for the new function, and
while we're at it, we can remove a null write to skb->next by replacing
it with skb_mark_not_on_list.
