xfrm: Force a dst refcount before entering the xfrm type handlers
Crypto requests might return asynchronous. In this case we leave
the rcu protected region, so force a refcount on the skb's
destination entry before we enter the xfrm type input/output
handlers.
This fixes a crash when a route is deleted whilst sending IPsec
data that is transformed by an asynchronous algorithm.
