Fixed a bug no error message for ALTER with InnoDB and AUTO_INCREMENT (Bug #7061).

sql/ha_innodb.cc:
  Fixed a bug no error message for ALTER with InnoDB and AUTO_INCREMENT (Bug #7061).
  It cant be put on commit because ALTER TABLE will commit on every 10000 rows.
  Therefore, this change must be done when a new temporary table is created
  in the ALTER TABLE.
