Ke Wang 6f8b7ac222 trace: sched: Fix util_avg_walt in sched_load_avg_cpu trace ...

cumulative_runnable_avg was introduced in commit ee4cebd75e ("sched:
EAS/WALT: use cr_avg instead of prev_runnable_sum") in cpu_util() for
task placement, which is used to replace prev_runnable_sum.

Fix util_avg_walt in sched_load_avg_cpu trace, which use prev_runnable_sum
for cpu_util().

Moreover, fix potential overflow due to cumulative_runnable_avg is in u64.
