  We need to define version 1 of nvme, not nvme_foo. Otherwise nvd won't load
  and people who pull in nvme/nvd from modules can't load nvd.ko since it
  depends on nvme, not nvme_foo. The duplicate doesn't matter since kldxref
  properly handles that case.

  It turns out the duplication is only mostly harmless.
