sctp: Remove useless last_time_used variable
The transport last_time_used variable is rather useless. It was only used when determining if CWND needs to be updated due to idle transport. However, idle transport detection was based on a Heartbeat timer and last_time_used was not incremented when sending Heartbeats. As a result the check for cwnd reduction was always true. We can get rid of the variable and just base our cwnd manipulation on the HB timer (like the code comment sais). We also have to call into the cwnd manipulation function regardless of whether HBs are enabled or not. That way we will detect idle transports if the user has disabled Heartbeats.
