Subject: [PATCH] CLEANUP: quic: Remove useless definitions from quic_cc_event
 struct

Since the persistent congestion detection is done out of the congestion
controllers, there is no need to pass them information through quic_cc_event struct.
We remove its useless members. Also remove qc_cc_loss_event() which is no more used.
