When the SSL object was destroyed, it would invalidate all SSL_SESSION
objects including the cached, but not yet used, TLS session objects.
Properly disassociate the SSL object from the SSL_SESSION before we
store it in the TLS session cache, so we can later destroy it without
invalidating the cached TLS sessions.
