Monty f386b70beb Honor lock_wait_timeout when updating stats tables ...

- Call delete_statistics_tables() after lock_table_names in drop tables.
  This avoids a deadlock issue with FTWRL and future backup locks.
- Added some missing clear_error()
- Ensure we don't clear error caused by the caller
- Updated function comments
