Just that disabling bluetooth also incorrectly disables wifi on those
models (the same as happens for other Dell models in the table?), but
they behave properly (their disable behaviors are no longer linked) once
added to the dell_blacklist table.

I'll resubmit the patch, with perhaps better wording, and since I've
been advised that the model name "XPS 15z" should actually be just "XPS
15".
