score: Remove unused default scheduler ops

If SMP support is enabled and the system has exactly one processor, then
it may use an uniprocessor scheduler.  The ask for help, reconsider help
request, and withdraw node operations can be NULL in this case, since
they are only used if a thread has at least one helping scheduler node.
At least two schedulers are required to get a helping node and each
scheduler involved must own at least one processor.  This is not
possible on a system with exactly one processor.
