The test attaches a SCSI controller to a non-zero slot and a pcie-to-pci bridge on slot 0 on the same pcie-root-port. Since a downstream device can be attached to a pcie-root-port only on slot 0, the above test configuration is not allowed. Additionally using pcie.0 as id for pcie-to-pci bridge is incorrect as that id is reserved only for the root bus. In the test scenario, there is no need to attach a pcie-root-port to the root complex. A SCSI controller can be attached to a pcie-to-pci bridge which can then be directly attached to the root bus (pcie.0). Fix the test and simplify it.
