blk-throttle: remove more latency dead-code
The struct 'latency_bucket' and the #define 'request_bucket_index'
are unused since
commit bf20ab538c81 ("blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW")
and the 'LATENCY_BUCKET_SIZE' #define was only used by the
'request_bucket_index' define.
Remove them.
