pci_scan_child_bus_extend() complains when we assign an unreachable
secondary bus number to a bridge. For example, given the topology below:
+-1b.0-[01-39]----00.0-[02-3a]--+-00.0-[03]----00.0
+-01.0-[04-39]--
\-02.0-[3a]----00.0
it logs the following messages:
pci_bus 0000:3a: [bus 3a] partially hidden behind bridge 0000:02 [bus 02-39]
pci_bus 0000:3a: [bus 3a] partially hidden behind bridge 0000:01 [bus 01-39]
These messages are incorrect (0000:02 is a bus, not a bridge) and
confusing. Make the message more understandable:
pci 0000:02:02.0: devices behind bridge are unusable because [bus 3a] cannot be assigned for them
Also, remove the reference to CardBus, because this issue affects all
varieties of PCI, not just CardBus.
