I think in this case, it's mostly a matter of consistency... pretty much
everything that returns a device_node grabs a reference... except
pci_device_to_OF_node :-)

I think Michael is trying to address that, and axon-msi happens to be
something he wrote so a good candidate for an initial conversion :-)
