QUIC: update packet length for short packets too. During long packet header parsing, pkt->len is updated with the Length field value that is used to find next coalesced packets in a datagram. For short packets it still contained the whole QUIC packet size. This change uniforms packet length handling to always contain the total length of the packet number and protected packet payload in pkt->len.
