Daniel Verkamp 474632ba7b bdev/nvme: simplify spdk_bdev_nvme_get_ctrlr()
Rather than iterating over the g_nvme_bdevs list to determine if a bdev
is an NVMe bdev, we can just compare the module pointer.

Also, the function can take a spdk_bdev pointer directly rather than
casting from a void pointer.
