[php-src] PR #25132: openssl: Fix use-after-free in TLS session remove callback

Pull Request: https://github.com/php/php-src/pull/25132 Author: bukka The session remove callback reads the listener stream from the SSL_CTX ex_data, but the context is shared with accepted connections and can outlive the listener. Closing the listener left a dangling pointer that the callback later dereferenced. Clear it on close when it refers to the stream being freed. The added test reproduces it via a TCP proxy and crashes under ASan without the fix.
