          Description

          After MDEV-3808 we have persistent table metadata versions stored in frm files.
          Now we can remove that temporary workaround that uses table_map_id
          in TABLE_SHARE::get_table_ref_version(). Using non-persistent versions
          causes unnecessary re-prepares of prepared statements, because a table will be
          erroneously identified as ALTER-ed when it's simply closed and reopened.
