SSL: ngx_ssl_shutdown() rework. Instead of calling SSL_free() with each return point, introduced a single place where cleanup happens. As a positive side effect, this fixes two potential memory leaks on ngx_handle_read_event() and ngx_handle_write_event() errors where there were no SSL_free() calls (though unlikely practical, as errors there are only expected to happen due to bugs or kernel issues).
