sd: only call disk_clear_zoned when needed

disk_clear_zoned only needs to be called when a device reported zone
managed mode first and we clear it. Add a check so that disk_clear_zoned
isn't called on devices that were never zoned.

This avoids a fairly expensive queue freezing when revalidating
conventional devices.
