In order to make multi-delete SP friendly we need to have all table locks for the elements of main statement table list properly set at the end of parsing. Also performed small cleanup: We don't need relink_tables_for_multidelete() any longer since the only case now when TABLE_LIST::correspondent_table is non-zero are tables in auxilary table list of multi-delete and these tables are handled specially in mysql_multi_delete_prepare().
