The change is also unnecessary because the attribute was
already validated and the length can not be less than zero.

Since act_simple is an academic example:
I think that a better solution is to add TCA_DEF_DATA (which is a
string) to the nla_policy. nla_policy is defined but at the moment it is
not used in the call to nla_parse_nested() - might as well use it.

Basic validity checks are always performed. But I agree, better
to provide a good example.
