Point is not that it has to be initialized first, point is it has to be 
initialized only _once_.
So when moving it into a separate module we cannot use the Makefile 
trick from Christoph, and when initialized it in nvme-core we have a
dependency on nvme-core from nvmet.
Which would be the easiest way (ie have nvmet dependent on nvme-core),
but no sure if that's the way we want to go.
