x86/topology: Don't evaluate logical IDs during early boot

Browse Source 
The local APICs have not yet been enumerated so the logical ID evaluation
from the topology bitmaps does not work and would return an error code.

Skip the evaluation during the early boot CPUID evaluation and only apply
it on the final run.
