smtp: Fixed handling of multiline server greeting responses

Incorrectly processed multiline server greeting responses as "wanted"
continue responses in smtp_endofresp(), from commit f16c0de4e9bbe3,
which in turn broke the SMTP server detection in the test suite,
because the EHLO command would not be sent.
