fix handling of close_notify (ssl) in http with openssl bufferevents

Since it can arrive after we disabled events in that bufferevent and
reseted fd, hence evhttp_error_cb() could be called after
SSL_RECEIVED_SHUTDOWN.

Closes: #557

           an API for "stop connecting", or use bufferevent_setfd to turn off
