crosvm: Preserve order of early hotplugged device
When multiple PCI devices are hotplugged in before PCI enumeration, the
devices may be listed in a different order than they are hotplugged.
This CL fixes the issue by allocating hotplug ports in the same order as
they would be enumerated by the guest OS.

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.
