cpumask: limit visibility of FORCE_NR_CPUS

In current form, FORCE_NR_CPUS is visible to all users building their

allyesconfig, which is not a correct behavior.

This patch fixes it.  It also changes the parameter short description:
removes implementation details and highlights the effect of the change.
