("tools/virtio: fix virtio_test.c") indentation is actually cosmetic.
("vhost: Not cleaning batched descs in VHOST_SET_VRING_BASE ioctl")
just avoid to clean batches descriptors for a third time (they are
cleaned on backend removal and addition).
("vhost: Fix bad order in vhost_test_set_backend at enable") is
actually a fix, the test does not work properly without it. And
("tools/virtio: Reset index in virtio_test --reset.") Makes the test
work more similar than the actual VM does in a reset.
("tools/virtio: Use __vring_new_virtqueue in virtio_test.c") and
("tools/virtio: Extract virtqueue initialization in vq_reset") are
convenience commits to reach the previous two.
Lastly, ("tools/virtio: Use tools/include/list.h instead of stubs")
just removes stub code, I did it when I try to test vdpa code and it
seems to me a nice to have, but we can drop it from the patchset if
you don't see that way.

Sorry, I will try to keep an eye on that from now on. I will send a v2
with Signed-off-by and extended descriptions if you see it ok.
Thanks!
