Fixed log action when using SSL certificates with variables. When variables are used in ssl_certificate or ssl_certificate_key, a request is created in the certificate callback to evaluate the variables, and then freed. Freeing it, however, updates c->log->action to "closing request", resulting in confusing error messages like "client timed out ... while closing request" when a client times out during the SSL handshake. Fix is to restore c->log->action after calling ngx_http_free_request().
