Changes in v6:
* Dropped continuations, the sysctl now returns after 64 iteration if necessary
Why? The caller should reasonably expect a single hypercall to complete,
not to have to reissue repeated to get all the data they want.
The caller is expected to restart from first_dev, not from beginning.
* -ENODEV returned if device is not found
You don't actually break on -ENODEV, which causes the loop to continue
to new devices and leave no hint as to which device doesn't exist.
Doh, I must have lost the break during various merges.
