 score: Allocate per-CPU data only if necessary

 The _Workspace_Allocate_aligned() would returns a non-NULL pointer for a
 zero size allocation request if there is enough memory available.  This
 conflicts with the size estimate of zero in
 _Workspace_Space_for_per_CPU_data() if the per-CPU data set is empty.

 Update #3507.
