numa-balancing: fix confusion in /proc/sys/kernel/numa_balancing

We can only echo 0 or 1 > "/proc/sys/kernel/numa_balancing", usually 1 means enable and 0 means disable. But when echo 1, it shows the value is 65536, this is confusion.

So in the latest scheduler tree this variable got renamed, please adjust your patch:
