====================
skb_list_walk_safe refactoring for net/*'s skb_gso_segment usage

This patchset adjusts all return values of skb_gso_segment in net/* to
use the new skb_list_walk_safe helper.

First we fix a minor bug in the helper macro that didn't come up in the
last patchset's uses. Then we adjust several cases throughout net/. The
xfrm changes were a bit hairy, but doable. Reading and thinking about
the code in mac80211 indicates a memory leak, which the commit
addresses. All the other cases were pretty trivial.
