Ani Sinha ca92eb5def hw/pci: warn when PCIe device is plugged into non-zero slot of downstream port 
PCIe downstream ports only have a single device 0, so PCI Express devices can
only be plugged into slot 0 on a PCIe port. Add a warning to let users know
when the invalid configuration is used. We may enforce this more strongly later
once we get more clarity on whether we are introducing a bad regression for
users currently using the wrong configuration.

The change has been tested to not break or alter behaviors of ARI capable
devices by instantiating seven vfs on an emulated igb device (the maximum
number of vfs the igb device supports). The vfs are instantiated correctly
and are seen to have non-zero device/slot numbers in the conventional PCI BDF
representation.
