BUG/MEDIUM: quic: Possible crash in ha_quic_set_encryption_secrets()

This bug has come with this commit:
   1fc5e16c4 MINOR: quic: More accurate immediately close
As mentionned in this commit we do not want to derive anymore secret when in closing
state. But the flag which denote secrets were derived was set. Add a label at
the correct flag to skip the secrets derivation without setting this flag.
