BUG/MINOR: quic: Avoid sending useless PADDING frame

This may happen in rare cases with extreme packet loss (30% for both TX and RX)
which leads the congestion window to decrease down to its minimal value (two
datagrams). Under such circumtances, no ack-eliciting frame can be added to
a packet by qc_build_frms(). In this case we must cancel the packet building
process if there is no ACK or probe (PING frame) to send.
