I think I must have been copying the existing code, which checks for
pdev_path of disk (rather than in_disk, which is what's being passed to
this function).

In the next patch this will also be called from the devicemodel code,
but that code dereferences disk[i].pdev_path (implicitly assuming that
it will never be null), so I think we can drop this check.

Ack on the other two comments.
