Possible use of destroyed pool objects

[kpschoedel]

Problem

Historically, objects allocated from a pool have not been destroyed or flagged when the pool is destroyed. https://github.com/project-chip/connectedhomeip/runs/4228395289 appears be failing due to an object (TCPEndPoint) outliving its pool.
