Paolo Bonzini ad07cd69ec virtio-scsi: always use dataplane path if ioeventfd is active 
Override start_ioeventfd and stop_ioeventfd to start/stop the
whole dataplane logic.  This has some positive side effects:

- no need anymore for virtio_add_queue_aio (i.e. a revert of
  commit 1c627137c1)

- no need anymore to switch from generic ioeventfd handlers to
  dataplane

It detects some errors better:

    $ qemu-system-x86_64 -object iothread,id=io \
          -device virtio-scsi-pci,ioeventfd=off,iothread=io
    qemu-system-x86_64: -device virtio-scsi-pci,ioeventfd=off,iothread=io:
    ioeventfd is required for iothread

while previously it would have started just fine.
