lru_cache: use correct type in sizeof for allocation
This has no actual effect, since sizeof(struct hlist_head) ==
sizeof(struct hlist_head *), but it's still the wrong type to use.
The semantic match that finds this problem:
// <smpl>
@@
type T;
identifier x;
@@
T *x;
...
* x = kzalloc(... * sizeof(T*) * ..., ...);
// </smpl>
