BUG/MINOR: quic: Wrong token length check (quic_generate_retry_token())

This bug would never occur because the buffer supplied to quic_generate_retry_token()
to build a Retry token is large enough to embed such a token. Anyway, this patch
fixes quic_generate_retry_token() implementation.

There were two errors: this is the ODCID which is added to the token. Furthermore
the timestamp was not taken into an account.

Must be backported to 2.6 and 2.7.
