PCI: aardvark: Simplify initialization of rootcap on virtual bridge

commit 454c5327 upstream.

PCIe config space can be initialized also before pci_bridge_emul_init()
call, so move rootcap initialization after PCI config space initialization.

This simplifies the function a little since it removes one if (ret < 0)
check.
