MDEV-25549 : Assertion `*new_engine' failed in bool check_engine(THD*, const char*, const char*, HA_CREATE_INFO*)

Browse Source 
In Galera case we call check_engine that could set create_info->db_type
to NULL e.g. if TEMPORARY is not supported by storage engine. Thus,
we need to restore it after that call because it is needed later
on mysql_create_table that will also call check_engine.
