smp: Remove preempt_disable() from smp_call_function()
smp_call_function_many_cond() handles the preemption and CPU pinning
requirements internally. smp_call_function() only forwards the request to
that helper for cpu_online_mask and does not access CPU-local state on
its own.
Remove the outer preempt_disable() and preempt_enable() pair from
smp_call_function().
