bdev_nvme: allow bdev_nvme_create() to take a NULL names arg

Browse Source 
We will want to use bdev_nvme_create() to attach to
controllers identified through discovery.  In this case,
we won't be reporting bdev names back to an RPC caller,
so there's no need to allocate an array of names to be
filled out since they won't be used.
