submission-login: Fix setting the default submission_max_mail_size=unlimited

Pre-login default value is intended to be unlimited, while post-login
default value is 40 MB, unless overridden by the relay server.

The old code was relying on the default settings struct being different for
submission and submission-login, which was rather kludgy. This also wasn't
visible in doveconf output.
