Daniel Verkamp 659252d103 devices: pci: propagate PciRoot add_device errors 
Rather than just printing an error and continuing, this makes the errors
fatal when adding a PCI device with invalid configuration (e.g. an
address on the wrong bus) at startup time. Hotplug errors are still
considered non-fatal and execution continues in that case.

BUG=None
TEST=crosvm run --stub-pci-device 2:00.0,...

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
