block/iocost: silence warning on 'last_period' potentially being unused
If CONFIG_TRACEPOINTS isn't enabled, we assign this variable but then
never use it. This can cause the compiler to complain about that:
block/blk-iocost.c:1264:6: warning: variable 'last_period' set but not used [-Wunused-but-set-variable]
1264 | u64 last_period, cur_period;
| ^
Rather than add ifdefs to guard this, just mark it __maybe_unused.
