While reviewing https://github.com/infinispan/infinispan/pull/10818 it was noticed that maxIdle should never touch the metadata. In fact the code is never even used as the lines here

https://github.com/infinispan/infinispan/blob/main/core/src/main/java/org/infinispan/container/offheap/OffHeapEntryFactoryImpl.java#L616-L629

One of those has to be true at that point, so it can't even use the code after it. We should remove the code to prevent confusion and simplify code.
