Log:
  Add NVMe drive to NOIOB quirk list
  
  Dell-branded Intel P4600 NVMe drives benefit from NVMe 1.3's NOIOB
  feature. Unfortunately just like Intel DC P4500s, they don't advertise
  themselves as benefiting from this...
  
  This changes adds P4600s to the existing list of old drives which
  benefit from striping.
