sched/topology: Refinement to topology_span_sane speedup

Browse source

Simplify the topology_span_sane code further, removing the need to
allocate an array and gotos used to make sure the array gets freed.

This version is in a separate commit because it could return a
different sanity result than the previous code, but only in odd
circumstances that are not expected to actually occur; for example,
when a CPU is not listed in its own mask.
