KVM: x86: Make kvm_lapic_set_reg() a "private" xAPIC helper
Hide the lapic's "raw" write helper inside lapic.c to force non-APIC code
to go through proper helpers when modification the vAPIC state. Keep the
read helper visible to outsiders for now, refactoring KVM to hide it too
is possible, it will just take more work to do so.
No functional change intended.
