PCI: Add root bus children dev's res to fail list

We can stop trying according to try_number now and do not need to use root_bus checking as stop sign. In extreme case we could need to reallocate resource for device just under root bus. For PCI root bus hot-add, we need to retry to assign resources to PCI devices just under pci root bus.
