      xen-netback: Don't destroy the netdev until the vif is shut down
      
      [ upstream commit id: 279f438e36c0a70b23b86d2090aeec50155034a9 ]
      
      Without this patch, if a frontend cycles through states Closing
      and Closed (which Windows frontends need to do) then the netdev
      will be destroyed and requires re-invocation of hotplug scripts
      to restore state before the frontend can move to Connected. Thus
      when udev is not in use the backend gets stuck in InitWait.
      
      With this patch, the netdev is left alone whilst the backend is
      still online and is only de-registered and freed just prior to
      destroying the vif (which is also nicely symmetrical with the
      netdev allocation and registration being done during probe) so
      no re-invocation of hotplug scripts is required.

      xen-netback: Don't destroy the netdev until the vif is shut down
      
      [ upstream commit id: 279f438e36c0a70b23b86d2090aeec50155034a9 ]
      
      Without this patch, if a frontend cycles through states Closing
      and Closed (which Windows frontends need to do) then the netdev
      will be destroyed and requires re-invocation of hotplug scripts
      to restore state before the frontend can move to Connected. Thus
      when udev is not in use the backend gets stuck in InitWait.
      
      With this patch, the netdev is left alone whilst the backend is
      still online and is only de-registered and freed just prior to
      destroying the vif (which is also nicely symmetrical with the
      netdev allocation and registration being done during probe) so
      no re-invocation of hotplug scripts is required.
