  auth: Fix default SASL bind for LDAP

User may configure Dovecot to use SASL bind as default bind method.  This can
be the case when ldapi:/// (or ldaps:///) with SASL EXTERNAL is used.
Currently, Dovecot returns LDAP connection to wrong bind state after first
successful auth bind, LDAP simple bind always used to rebind.  This may broke
setup when ACL in LDAP configured not to allow search/bind for such simple
bind.
