From: Johannes Berg <johannes.berg@xxxxxxxxx>
This was another workaround for truesize "bugs".
The reason we did this was that when we orphaned
the SKB it wouldn't be truesize-checked later.
Now that the check is gone (and we just charge
the former smaller size to the socket) there's
no longer a reason to orphan the skb here.
Keep the skb charged to the socket until it is
really freed (or orphaned in TX status). This
helps flow control and allows us to get at the
socket later for other purposes.
