Subject: [PATCH] row0ins.c:   Fix bug: FOREIGN KEY ... ON UPDATE/DELETE NO
 ACTION must check the foreign key constraint, not ignore it. Peter Gulutzan
 said that NO ACTION should check the constraint as deferred, at the end of
 the SQL statement, while RESTRICT should check it immediately. Since we do
 not have defered constraints in InnoDB, this bug fix makes InnoDB to check NO
 ACTION constraints immediately, like it checks RESTRICT constraints.
