virtio_blk: Do not use disk_set_max_open/active_zones()
In virtblk_read_zoned_limits(), setting a zoned block device maximum number of open and active zones using the functions disk_set_max_open_zones() and disk_set_max_active_zones() is incorrect as setting the limits for the request queue is now done atomically when the gendisk is created (with blk_mq_alloc_disk()). The value set by the disk_set_max_open/active_zones() functions will be overwritten. Fix this by setting the maximum number of open and active zones directly in the queue_limits structure passed to virtblk_read_zoned_limits().
