modesetting: Fix PCI initialization on non-zero domains 

libdrm's busid matching for the legacy three-integer bus string format
simply ignores the domain number, rather than what we were doing here of
packing the domain into the bus number. Whatever, just use the existing
code to build a busid string, since that gets the domain right.
