MDEV-11412 Ensure that table is truly dropped when using DROP TABLE

Browse Source 
don't do table discovery on DROP. DROP falls back to "force"
approach when a table isn't found and will try to drop in all
engines anyway. That is, trying to discover in all engines before
the drop is redundant and may be expensive.
