x86/mtrr: Remove get_online_cpus() from mtrr_save_state()
mtrr_save_state() is invoked from native_cpu_up() which is in the context
of a CPU hotplug operation and therefor calling get_online_cpus() is
pointless.
While this works in the current get_online_cpus() implementation it
prevents from converting the hotplug locking to percpu rwsems.
Remove it.
