Hillf Danton 7142d17e8f sched: Shorten the construction of the span cpu mask of sched domain ...

For a given node, when constructing the cpumask for its
sched_domain to span, if there is no best node available after
searching, further efforts could be saved, based on small change
in the return value of find_next_best_node().
