block: add zone write plug condition to debugfs zone_wplugs 



Modify queue_zone_wplug_show() to include the condition of a zone write
plug to the zone_wplugs debugfs attribute of a zoned block device.
To improve readability and ease of use, rather than the zone condition
raw value, the zone condition name is given using blk_zone_cond_str().
