block: don't handle bio based drivers in blk_revalidate_disk_zones
bio based drivers only need to update q->nr_zones. Do that manually
instead of overloading blk_revalidate_disk_zones to keep that function
simpler for the next round of changes that will rely even more on the
request based functionality.
