Revert "smp/cpumask: Make CONFIG_CPUMASK_OFFSTACK=y usable without debug dependency"

This reverts commit 9dd1220114e00d8ec5cdc20085bbe198b21e1985.

Revert it until Linus's concerns are addressed: this option should not
allow nonsensical CONFIG_CPUMASK_OFFSTACK and CONFIG_NR_CPUS values, and
it should probably select sane defaults as well.

          Use dynamic allocation for cpumask_var_t, instead of putting
          them on the stack.  This is a bit more expensive, but avoids
