x86_32: apic/es7000_32, cpu_mask_to_apicid cleanup
Remove es7000_cpu_mask_to_apicid_cluster completely, because it's almost the same as es7000_cpu_mask_to_apicid except 2 code paths. One of them is about to be removed soon, the another should be BAD_APICID (it's a fail path). The _cluster one was not invoked on apic->cpu_mask_to_apicid_and anyway, since there was no _cluster_and variant. Also use newer cpumask functions.
