[PATCH v2 10/13] PCI: aardvark: Simplify initialization of rootcap on virtual bridge

["Marek Behún" <kabel@kernel.org>]

From: Pali Rohár <pali@kernel.org>

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.
