Not supplying "integrity" as an "lsm=" option is a user error. There
are only two options - allow or deny the caller to proceed. If the
user is expecting the integrity subsystem to be properly working,
returning a NULL and allowing the system to boot (RFC patch version)
does not make sense. Better to fail early.
