xend: pass-through: fix regression in the ordering of the output of xm pci list

changeset "python: Remove tab indents" (19937:e845326ae203)
introduces a minor regression in the multi-function PCI pass-through
code by causing bogus return values from the sort function
which is used to order the output of "xm pci list".
