[PATCH] Fix SASL operations through TLS

[Enrico Scholz]

SASL operations through TLS do not work as the custom 'writeln()'
operation would skip the gnutls_record_send() call unconditionally
('len' is initialized to 0 and won't be modified).

This patch initializes 'len' with the length of the string and
reuses this value in the following send/write calls.
