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().
Fixes: 8b837256560c ("virtio_blk: pass queue_limits to blk_mq_alloc_disk")
