[SCTP]: Increment error counters on user requested HBs.

2960bis states (Section 8.3):

   D) Request an on-demand HEARTBEAT on a specific destination transport
      address of a given association.

   The endpoint should increment the respective error counter of the
   destination transport address each time a HEARTBEAT is sent to that
   address and not acknowledged within one RTO.
