[PATCH 3/7] the key of hash table should include the function value

[Wen Congyang <wency@xxxxxxxxxxxxxx>]

We save all used PCI address in the hash table. The key is generated by domain,
bus and slot now. We will support multi function PCI device, so the key should
be generated by domain, bus, slot and function.
