ynl: ensure exact-len value is resolved
For type String and Binary we are currently usinig the exact-len limit value as is without attempting any name resolution. However, the spec may specify the name of a constant rather than an actual value, which would result in using the constant name as is and thus break the policy. Ensure the limit value is passed to get_limit(), which will always attempt resolving the name before printing the policy rule.
