[PATCH 06/16] nvmet: use blk_queue_zone_no()

[Pankaj Raghav]

From: Luis Chamberlain <mcgrof at kernel.org>

Instead of open coding the number of zones given a sector, use the helper
blk_queue_zone_no(). This let's us make modifications to the math if
needed in one place and adds now support for npo2 zone devices.
