Michael Brown 95e756569a [pci] Ignore invalid subordinate bus numbers ...

Some systems (observed on a Dell C6615) fail to correctly populate the
subordinate PCI bus number on some PCI bridges.  We do not currently
guard against this behaviour, causing us to subsequently scan through
a huge expanse of the PCI bus:dev.fn address range.

Fix by ignoring the subordinate bus number if it is lower than the
bridge's own bus number.
