nvme_zone_mgmt_recv uses nvme_ns_nlbas() to get the number of LBAs in
the namespace and then calculates the number of zones to report by
incrementing slba with ZSZE until exceeding the number of LBAs as
returned by nvme_ns_nlbas().
This is bad because the namespace might be of such as size that some
LBAs are valid, but are not part of any zone, causing zone management
receive to report one additional (but non-existing) zone.
Fix this with a conventional loop on i < ns->num_zones instead.
