smp: Remove preempt_disable() from on_each_cpu_cond_mask()

Browse source

smp_call_function_many_cond() handles the preemption and CPU pinning
requirements internally. on_each_cpu_cond_mask() only builds the call
flags and forwards the request to that helper.

Remove the outer preempt_disable() and preempt_enable() pair from
on_each_cpu_cond_mask().
