netem: fix skb_orphan_partial()
commit f6ba8d33cfbb46df569972e64dbb5bb7e929bfd9 upstream.
I should have known that lowering skb->truesize was dangerous :/
In case packets are not leaving the host via a standard Ethernet device,
but looped back to local sockets, bad things can happen, as reported
by Michael Madsen ( https://bugzilla.kernel.org/show_bug.cgi?id=195713 )
So instead of tweaking skb->truesize, lets change skb->destructor
and keep a reference on the owner socket via its sk_refcnt.
Fixes: f2f872f9272a ("netem: Introduce skb_orphan_partial() helper")
