Alexander Gordeev 214e270b5f x86/apic/es7000+summit: Always make valid apicid from a cpumask 
In case of invalid parameters cpu_mask_to_apicid_and() might
return apicid value of 0 (on Summit) or a uninitialized value
(on ES7000), although it is supposed to return apicid of cpu-0
at least. Fix the operation to always return a valid apicid.
