Incorrect definition of server's default port

[akito1986]

Server's default port is defined by frontend's port.
Although when server's port is undefined, this tool have occured below errors.

     HaproxyParser::FormatChecker::FormatError:

Maybe, default value's definition is incorrect.

Tentatively, I change server's port required.
