lucien f648f807f6 sctp: donot reset the overall_error_count in SHUTDOWN_RECEIVE state ... Commit f8d9605243 ("sctp: Enforce retransmission limit during shutdown") fixed a problem with excessive retransmissions in the SHUTDOWN_PENDING by not resetting the association overall_error_count. This allowed the association to better enforce assoc.max_retrans limit. However, the same issue still exists when the association is in SHUTDOWN_RECEIVED state. In this state, HB-ACKs will continue to reset the overall_error_count for the association would extend the lifetime of association unnecessarily. This patch solves this by resetting the overall_error_count whenever the current state is small then SCTP_STATE_SHUTDOWN_PENDING. As a small side-effect, we end up also handling SCTP_STATE_SHUTDOWN_ACK_SENT and SCTP_STATE_SHUTDOWN_SENT states, but they are not really impacted because we disable Heartbeats in those states.
