[CCID3]: Redundant debugging output / documentation

Each time feedback is sent two lines are printed:

	ccid3_hc_rx_send_feedback: client ... - entry
	ccid3_hc_rx_send_feedback: Interval ...usec, X_recv=..., 1/p=...

The first line is redundant and thus removed.

Further, documentation of ccid3_hc_rx_sock (capitalisation) is made consistent.
