SSL: logging level of "application data after close notify". Such fatal errors are reported by OpenSSL 1.1.1, and similarly by BoringSSL, if application data is encountered during SSL shutdown, which started to be observed on the second SSL_shutdown() call after SSL shutdown fixes made in 09fb2135a589 (1.19.2). The error means that the client continues to send application data after receiving the "close_notify" alert (ticket #2318). Previously it was reported as SSL_shutdown() error of SSL_ERROR_SYSCALL.
