Log:
  MFC r263277:
  
  nvme: Remove the software progress marker SET_FEATURE command during
  controller initialization.
  
  The spec says OS drivers should send this command after controller
  initialization completes successfully, but other NVMe OS drivers are
  not sending this command.  This change will therefore reduce differences
  between the FreeBSD and other OS drivers.
