From: James Smart <jsmart2...@gmail.com>
A recent change added a numa_node field to the nvme controller
and has the transport assign the node using dev_to_node().
However, fcloop registers with a NULL device struct, so the
dev_to_node() call oops.
Revise the assignment to assign no node when device struct is null.
Fixes: 103e515efa89b ("nvme: add a numa_node field to struct nvme_ctrl")
