PCI: Prevent NULL dereference during pciehp probe pciehp assumes that dev->subordinate exists. But we do not assign a bus if we run out of bus numbers during enumeration. This leads to a NULL dereference in init_slot() (and other places). Change pciehp_probe() to return -ENODEV when no subordinate bus is present.
