smtp.c: Re-factored smtp_auth_login_user() for use with passwords

In preparation for moving to the SASL module re-factored the
smtp_auth_login_user() function to smtp_auth_login() so that it can be
used for both user names and passwords as sending both of these under
the login authentication mechanism is the same.
