credit1: replace cpumask_empty() uses

In one case it was redundant with the operation it got combined with,
and in the other it could easily be replaced by range checking the
result of a subsequent operation. (When running on big systems,
operations on CPU masks aren't cheap enough to use them carelessly.)
