pci server crashes during boot on Qubes OS

I tried to launch Minix3 in Qubes OS. While there is no problem to boot minix as a qube (in Qubes OS terminology) before 3641562, it fails with the commit (and after). I didn't digg into PCI handling but this change fixes the problem. Minix handles NULL case from pci_subclass_name.
