x86: fix stack overflow for large values of MAX_APICS physid_mask_of_physid() causes a huge stack (12k) to be created if the number of APICS is large. Replace physid_mask_of_physid() with a new function that does not create large stacks. This is a problem only on large x86_64 systems. this paves the way to increase MAX_APICS.
