Discarding Handshake packets if no Handshake keys yet. Found with a previously received Initial packet with ACK only, which instantiates a new connection but do not produce the handshake keys. This can be triggered by a fairly well behaving client, if the server stands behind a load balancer that stripped Initial packets exchange. Found by F5 test suite.
