Before commit 7b5436635800 the pci_host_bridge was created before the root bus. As that commit has added a needless dependency on the bus for pci_alloc_host_bridge() the creation order has been changed for no good reason. Revert the order of creation as we are going to depend on the pci_host_bridge structure to retrieve the domain number of the root bus.
