[PATCH] x86: Put the num_processors++ code in a more suitable position

[Dou Liyang]

This is a code optimization.

If checking the topology package map of apicid and cpu is failure,
it will stop generating the processor info for that apicid and the
disabled_cpus will plus one. However, the num-processors has already
been added one above. That may cause the number of processors incorrect.

Just put the num_processors++ code in the more suitable position.
it makes sure that the num-processors will not conflict with the
disabled_cpus.
