module/sched: Fix None check

Browse Source 
As mentioned in the previous commit, CPU numbers would be passed to
SchedProcFSData's __init__() (instead of a proper sysfs path). When
done with CPU0, that path would be evaluated as False and the code
would carry on with the default path, which was quite confusing.

This has now been fixed (and 0 isn't such a great path to give
anyway), nevertheless this check should just catter to None.
