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.
