Sergey Vojtovich a3c980b381 MDEV-10824 - Crash in CREATE OR REPLACE TABLE t1 AS SELECT spfunc()
Code flow hit incorrect branch while closing table instances before removal.
This branch expects thread to hold open table instance, whereas CREATE OR
REPLACE doesn't actually hold open table instance.

Before CREATE OR REPLACE TABLE it was impossible to hit this condition in
LTM_PRELOCKED mode, thus the problem didn't expose itself during DROP TABLE
or DROP DATABASE.

Fixed by adjusting condition to take into account LTM_PRELOCKED mode, which can
be set during CREATE OR REPLACE TABLE.
