'virPCIDeviceList' is actually an array. Removing one element makes the rest of the element move.
Use while loop, increase index only when not virPCIDeviceListDel(pcidevs, dev)

'i--;' before that 'continue;' that's not in the index would be shorter, but I guess this is more readable. Or maybe: for (i = virPCIDeviceListCount(pcidevs); i > 0; i--) { size_t dev_index = i - 1; would just deal with this. Anyway, this works just as it is, ACK if you don't want to change it.
