BUG/MINOR: quic: Unckecked encryption levels availability

Browse Source 
This bug arrived with this commit:

   MEDIUM: quic: Dynamic allocations of QUIC TLS encryption levels

It is possible that haproxy receives a late Initial packet after it has
released its Initial or Handshake encryption levels. In this case
it must not try to retransmit packets from such encryption levels to
speed up the handshake completion.

No need to backport.
