sched/cputime: Rename vtime_accounting_enabled() to vtime_accounting_cpu_enabled() vtime_accounting_enabled() checks if vtime is running on the current CPU and is as such a misnomer. Lets rename it to a function that reflect its locality. We are going to need the current name for a function that tells if vtime runs at all on some CPU.
