tests: Fix duplicated capabilities

A bunch of SCSI test cases in qemuxml2argv used

  DO_TEST(...
          QEMU_CAPS_VIRTIO_SCSI, QEMU_CAPS_VIRTIO_SCSI,
          ...);

instead of the intended

  DO_TEST(...
          QEMU_CAPS_VIRTIO_SCSI, QEMU_CAPS_SCSI_LSI,
          ...);

which is used correctly in qemuxml2xml. Fix them.
