Rik van Riel c3f7f2c7eb smp: use __cpumask_set_cpu in on_each_cpu_cond ...

The code in on_each_cpu_cond sets CPUs in a locally allocated bitmask,
which should never be used by other CPUs simultaneously. There is no
need to use locked memory accesses to set the bits in this bitmap.

Switch to __cpumask_set_cpu.
