Ah, yes, I thought there was something that was done differently from
sparc.  Only printing non-zero domains seems like the right thing to
do, since it preserves backwards-compatibility.

Speaking of pci_name_bus(), it's amazing "folks" would introduce new
APIs that take a string buffer argument _without_ a size argument...
