It is already there in the middle of the realize function. It is moved to nvme_init_namespace as n->ns_size = bs_size; since only a single namespace can be configured anyway. I will remove the for-loop that initializes multiple namespaces as well.

From: Klaus Jensen <k.jensen@samsung.com> Philippe suggested that I split up this already way too huge series (more than 50 patches now), so here goes. The first patch in this series fixes a small bug in the pci doorbell size calculation. Please consider cherry-picking this. The rest are refactorings. The "nvme: add max_ioqpairs device parameter" introduces the 'max_ioqpairs' device parameter, the meaning of which should be more intuitive than the existing 'num_queues' parameter.
