lib-ssl-iostream: Fix potential busy loop when handshake has failed

If the stream is already destroyed, handshaking should return -1 as error
instead of "more data needed".

This fixes at least a potential busy loop when login-proxy tries to connect
to a remote server with mismatching SSL certificate name. It was timing
sensitive though, only seeming to happen when running with valgrind.

This code has been there since 9d0640616c30701bed286034840facfb386db90e
