scsi: nvme: zns: Set zone limits before revalidating zones 



In nvme_revalidate_zones(), execute blk_queue_chunk_sectors() and
blk_queue_max_zone_append_sectors() to respectively set a ZNS namespace
zone size and maximum zone append sector limit before executing
blk_revalidate_disk_zones(). This is to allow the block layer zone
reavlidation to check these device characteristics prior to checking all
zones of the device.
