x86 mtrr: Remove (noop) lock_cpu_hotplug().
CPUs coming online sync themselves with current MTRR state at an
appropriate point anyway.
It's not actually possible to have a newly booted CPU immediately have
in-sync MTRR state anyway. It has to be synced up as part of normal
CPU bootstrap procedure. Which is what we do.
