This code that executes virPCIDeviceReset in all virPCIDevicePtr
objects of a given virPCIDeviceListPtr list is replicated twice
in the code. Putting it in a helper function helps with
readability.

Small nit pick here, I prefer arguments appearing in their order of
importance. That means, virHostdevManager is more important than the
virPCIDeviceList, because the manager is built on the top of virpci module.
