[PULL 4/6] virtio-scsi: prepare virtio_scsi_handle_cmd for dataplane

[Stefan Hajnoczi <stefanha@redhat.com>]

Prepare virtio_scsi_handle_cmd() to be used by both dataplane and
non-dataplane by making the condition for starting ioeventfd more
specific. This way it won't trigger when dataplane has already been
started.
