QUIC: Fix getting packet type in Long Header

This change should fix the Coverity Scan issue CID 1493488:
178                             ND_PRINT(", handshake");
>>> CID 1493488:  Control flow issues  (DEADCODE)
>>> Execution cannot reach this statement: "if (packet_type == QUIC_LH_...".
179                     else if (packet_type == QUIC_LH_TYPE_RETRY)
