[Cake] a possible optimization

[Dave Taht]

// This will cross one cache line per queue

struct cake_tin {
struct cake_flow flows;
u32 backlogs;
u32 tags; /* for set association */
u16 overflow_idx;
struct cake_host hosts; /* for triple isolation */
};

struct cake_tin_data {
// The prior layout crossed 6.
struct cake_tin queue[CAKE_QUEUES];
...
// abandon all hope ye who refactor here.
