Deleting an SSL Profile used by a listener sometimes causes the router to crash

Start a router with an SSL Profile for a listener.
Delete the listener via qdmanage
Now, delete the SSL Profile via qdmanage.
The router will crash in some cases.

This is because of the code in connection_manager.c

qd_connection_manager_delete_ssl_profile()

if (freed)
        DEQ_REMOVE(qd->connection_manager->config_ssl_profiles, ssl_profile);

The above tries to delete a freed reference.
