BUG/MEDIUM: ssl: SSL backend sessions used after free
This bug impacts only the backends. The sessions cached could be used after been
freed because of a missing write lock into ssl_sock_handle_hs_error() when freeing
such objects. This issue could be rarely reproduced and only with QUIC with
difficulties (random CRYPTO data corruptions and instrumented code).

Must be backported as far as 2.6.
