  Remove a superfluous and dangerous freeing of an SSL_CTX.
  
  The problem here is that multiple server sessions share
  a SSL_CTX. When one session ended, the SSL_CTX would be
  freed and set NULL, leaving the other sessions unable to
  function.
  
  The code being removed is superfluous because the SSL_CTX
  structures for servers will be properly freed when ast_ssl_teardown
  is called.
