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 1c627137c10ee2dcf59e0383ade8a9abfa2d4355)
- 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.
