It's possible for a heap in the residency LRU to outlive the
ResidencyManager. When this happens, some heap in the LRU will be
referencing the LRU head node. On destruction, the outstanding heap
will attempt to access the LRU head node after the memory has been
freed. This commit removes the LinkedList head node from the list
within the LinkedList destructor to fix the bug.
