[PATCH v4 07/12] virtio: add legacy init/size APIs
...ely avoid breaking old userspace builds.
It's not actually part of the UAPI - it was kept in the UAPI
header by mistake, and using it in kernel isn't necessary
and prevents us from making changes safely.
In particular, the APIs actually assume the legacy layout.
Add an internal kernel-only vring_legacy_init/vring_legacy_size.
