scsi: sd_zbc: Set zone limits before revalidating zones

In sd_zbc_revalidate_zones(), execute blk_queue_chunk_sectors() and
blk_queue_max_zone_append_sectors() to respectively set a ZBC device
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.

Since blk_queue_max_zone_append_sectors() already caps the device
maximum zone append limit to the zone size and to the maximum command
size, the max_append value passed to blk_queue_max_zone_append_sectors()
is simplified to the maximum number of segments times the number of
sectors per page.
