[PATCH 3/6] block: remove blk_zone_wplug_handle_zone_mgmt

[Christoph Hellwig <hch@lst.de>]

blk_zone_wplug_handle_zone_mgmt now only checks that zone reset and
zone finish operations are directed to a sequential write required
zone.  This has nothing to do with zone write plugs and is better
handled with other bio validity checks in submit_bio_noacct.
