Fixed that CREATE TABLE code used the right create_info

- The old code used the original create_info from lex, not the new one
  that includes more information (like OPT_OR_REPLACE).
  The bug was not discovered as the code in lock_table_named() only
  checked for OPT_OR_REPLACE in case of timeout errors.
  As lock_table_names will be fixed as part of BACKUP STAGE's, there
  is no changes in lock_table_names() in this commit.
- Removed also the 'temporary' copy of statement flags to thd for
  lock_table_names()
