BUG/MINOR: quic: Leak of frames to send.

Browse Source 
In very rare cases, it is possible that packet are detected as lost, their frames
requeued, then the connection is released without releasing for any reason (to
be killed because of a sendto() fatal failure for instance. Such frames are lost
and never release because the function which release their packet number spaces
does not release the frames which are still enqueued to be send.

Must be backported as far as 2.6.
