[PATCH] powerpc/mm: fix typo of cpumask_clear_cpu()

[Li Yang]

The function name of cpumask_clear_cpu was not correct.

This also implies that the CONFIG_HOTPLUG_CPU was never tested.
We are trying to add cpu hotplug for SMP suspend, but seeing the
following error(on 2.6.31 with context patches applied).
Any idea or suggestion?
