x86/smp: Remove pointless wmb()s from native_stop_other_cpus()
The wmb()s before sending the IPIs are not synchronizing anything.
If at all then the apic IPI functions have to provide or act as appropriate
barriers.
Remove these cargo cult barriers which have no explanation of what they are
synchronizing.
