sched/cpuacct: Rename parameter in cpuusage_write() for readability



The name of the 'reset' parameter to cpuusage_write() is quite confusing,
because the only valid value we allow is '0', so !reset is actually the
case that resets ...

Rename it to 'val' and explain it in a comment that we only allow 0.
