  Move NVME controller shutdown from being called as part of module unloading
  to being called through the newbus DEVICE_SHUTDOWN() path. This ensures that
  the NVME controller gets shut down before the device and bus disappear
  and prevents data corruption on shutdown on at least Samsung EVO 960 SSDs.
