I don't think it makes sense to complete the "unknown" value here ...
Thanks for pointing this out. I totally missed it.

Wrong header formatting style, and two lines between functions please.

This is taking the path to a block device, so this should complete
existing filenames.
Here the element:
<device path="iqn.2013-06.com.example:iscsi-pool"/>
We can't expect the completer to predict this, even though giving
PathLocalExisting completer can help show the local ones, I guess
I will add it anyway. Similarly the `target` can also have Path completer.

This parameter takes a host SCSI adapter name, which can be completed
from data from the nodedev driver.
virshCompleteEmpty is meant exclusively for user options which we can't
complete.
Turns out there is already a completer for it, will just use that, and be more
specific to get only scsi adapter.
