BUG/MAJOR: ssl: fix breakage caused by recent fix abf08d9

Recent commit abf08d9 ("BUG/MAJOR: connection: fix mismatch between rcv_buf's
API and usage") accidentely broke SSL by relying on an uninitialized value to
enter the read loop.

Many thanks to Cyril Bonté and Steve Ruiz for reporting this issue.
