RFC: nvme-pci: split the probe and reset handlers

[Christoph Hellwig]

Hi all,

this series split the nvme-pci probe handler to be separate from the reset
handler.  I've been wanting to do that for a while, but the bug report from
Gerd that was caused by confusing about the controller state in the reset
state required it to be expedited.
