mariadb-DebarunBanerjee 5a58935cb9 MDEV-33101 Server crashes when starting the server with innodb-force-recovery=6 and enabling the innodb_truncate_temporary_tablespace_now variable
The issue is introduced by "MDEV-28699: Shrink temporary tablespaces
without restart". SRV_FORCE_NO_LOG_REDO forces server to read only mode
and we don't initialize temporary tablespace in read only mode.

solution: innodb_truncate_temporary_tablespace_now should be no-op in
read only mode.
