Subject: [PATCH 4.16 20/47] nvme: fix extended data LBA supported setting

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Max Gurtovoy <maxg@...lanox.com>

commit c97f414c54a255f4f05a50a2625efaeee406e134 upstream.

This value depands on the metadata support value, so reorder the
initialization to fit.

Fixes: b5be3b392 ("nvme: always unregister the integrity profile in __nvme_revalidate_disk")
