[Xen-devel] [PATCH]xend: pci: improve the assignability checking

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

1) fix some small typos in util/pci.py;
2) find_all_the_multi_functions(): BDFs of a multi-function PCIe device could 
be different in all the 3 fields (bus, device, function), so we need 
self.find_parent() and list all the BDFs below the parent;
3) to assign a device of the must-be-co-assigned devices, we require all the 
related devices should be owned by pciback;
4) detect and disallow duplicate pci string specified in guest config file due 
to carelessness.
