policy: Do not return an error for invalid value during parsing (#9442)
s3:HardwareInfo was removed recently. Users having that admin action
stored in the backend will have an issue starting the server.

To fix this, we need to avoid returning an error in Marshal/Unmarshal
when they encounter an invalid action and validate only in specific
location.

Currently the validation is done and in ParseConfig().
