PCI: Use res->parent to check if resource is assigned

reassign_resources_sorted() uses resource_size() to select between
pci_assign_resource() and pci_reassign_resource(). Due to twisted way
bridge window sizing in pbus_size_mem() sets resource sizes to 0, it works
to match into IOV resources but that is going to be changed by an upcoming
change.

Replace resource_size() check with res->parent check that is the true
dividing line in between whether assign or reassign function should be used
for the resource.
