MINOR: quic: store the lost packets counter in the quic_cc_event element

Browse Source 
Upon loss detection, qc_release_lost_pkts() notifies congestion
controllers about the event and its final time. However it does not
pass the number of lost packets, that can provide useful hints for
some controllers. Let's just pass this option.
