      libxl: avoid blktap2 deadlock on cleanup
      
      Establishes correct cleanup behavior for blktap devices.  This patch
      implements the release of the backend device before calling for
      the destruction of the userspace component of the blktap device.
      
      Without this patch the kernel xen-blkback driver deadlocks with
      the blktap2 user control plane until the IPC channel is terminated by the
      timeout on the select() call.  This results in a noticeable delay
      in the termination of the guest and causes the blktap minor
      number which had been allocated to be orphaned.
