Fixes an issue where the webrtcbin would hangup when finalizing due to the sctpenc hanging up when finalizing. This occurred when the webrtcbin chose to use a sctp association ID already in use. The sctpenc would fail to reach the paused state, but startup a task anyways that was never stopped. This commit modifies the behavior to not choose sctp association IDs randomly, and instead only choose one that is free. It also prevents the sctpenc from starting up that task if it fails to reach the paused state. Fixes: #4188 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8607>
