Cool! I added a negative schema and parse test for each of domain, bus,
slot, and function before I pushed.

Yeah, I had thought of changing that, but if I changed the return of
this function, I would need to change the return type of
virDomainDeviceAddressIsValid(), and then
virDomainDeviceCCWAddressIsValid() (since it's used in
virDomainDeviceAddressIsValid() identically to
virDevicePCIAddressIsValid()). Fortunately it would have stopped there
(as all the uses of all three functions essentially behave as if they
returned bool anyway), but it seemed like a bit too much change
unrelated to fixing the bug.

I've finally pushed this patch. Thanks for the review!
