- The original 'disengage' ATA controller model does not work properly
  for all possible disk configurations.  Use the newly added ATA disk
  veto eventhandler to fit into all possible disk configuration.
- If the 'invalid LUN' happens on blkvsc controllers, return
  CAM_DEV_NOT_THERE so that CAM will not destroy attached disks under
  the blkvsc controllers.

a5aad6f58b hyperv/hn: Suspend and resume the backend properly upon MTU change. 
Suspend:
- Prevent the backend from being touched on TX path.
- Clear the RNDIS RX filter, and wait for RX to drain.
- Make sure that NVS see the chimney sending buffer and RXBUF
  disconnection, before unlink these buffers from the channel.

Resume:
- Reconfigure the RNDIS filter.
- Allow TX path to work on the backend.
- Kick start the TX eof task, in case the OACTIVE is set.

This fixes various panics, when the interface has traffic and MTU
is being changed.
