hfsc: reduce hfsc_sched to 14 cachelines hfsc_sched is huge (size: 920, cachelines: 15), but we can get it to 14 cachelines by placing level after filter_cnt (covering 4 byte hole) and reducing period/nactive/flags to u32 (period is just a counter, incremented when class becomes active -- 2**32 is plenty for this purpose, also, long is only 32bit wide on 32bit platforms anyway). cl_vtperiod is exported to userspace via tc_hfsc_stats, but its period member is already u32, so no precision is lost there either.
