xfs: simplify kmem_{zone_}zalloc
Introduce flag KM_ZERO which is used to alloc zeroed entry, and convert kmem_{zone_}zalloc to call kmem_{zone_}alloc() with KM_ZERO directly, in order to avoid the setting to zero step. And following Dave's suggestion, make kmem_{zone_}zalloc static inline into kmem.h as they're now just a simple wrapper. V2: Make kmem_{zone_}zalloc static inline into kmem.h as Dave suggested.
