Revision b7e97872a65e1d57b4451769610554c131f37a0a authored by Dennis Maisenbacher on 06 September 2022, 07:39:28 UTC, committed by Christoph Hellwig on 07 September 2022, 06:33:17 UTC 
nvmet: fix mar and mor off-by-one errors
 
Maximum Active Resources (MAR) and Maximum Open Resources (MOR) are 0's
based vales where a value of 0xffffffff indicates that there is no limit.

Decrement the values that are returned by bdev_max_open_zones and
bdev_max_active_zones as the block layer helpers are not 0's based.
A 0 returned by the block layer helpers indicates no limit, thus convert
it to 0xffffffff (U32_MAX).
