null_blk: Fix REQ_OP_ZONE_CLOSE handling
In order to match ZBC defined behavior, closing an empty zone must result in the "empty" zone condition instead of the "closed" condition. Fixes: da644b2cc1a4 ("null_blk: add zone open, close, and finish support") Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
