Original Commit Message:

  Prevent KeyUpdate for QUIC

  QUIC does not use the TLS KeyUpdate message/mechanism, and indeed
  it is an error to generate or receive such a message.  Add the
  necessary checks (noting that the check for receipt should be
  redundant since SSL_provide_quic_data() is the only way to provide
  input to the TLS layer for a QUIC connection).
