CVE-2023-52671

[Why] Under some circumstances, disabling an OPTC and attempting to reclaim its OPP(s) for a different OPTC could cause a hang/underflow due to OPPs not being properly disconnected from the disabled OPTC.

[How] Ensure that all OPPs are unassigned from an OPTC when it gets disabled.
