[PATCH] radeon: Test for PCI root bus before assuming bus->self

If we assign a Radeon device to a virtual machine, we can no longer assume a fixed hardware topology, like the GPU having a parent device. This patch simply adds a few pci_is_root_bus() tests to avoid passing a NULL pointer to PCI access functions, allowing the radeon driver to work in a QEMU 440FX
