Subject: cpumask: limit visibility of FORCE_NR_CPUS

In current form, FORCE_NR_CPUS is visible to all users building their
kernels, even not experts.  It is also set in allmodconfig or
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.

          Say Yes if you have NR_CPUS set to an actual number of possible
          CPUs in your system, not to a default value. This forces the core
