KVM: x86: Move CPU compat checks hook to kvm_x86_ops (from kvm_x86_init_ops)
Move the .check_processor_compatibility() callback from kvm_x86_init_ops
to kvm_x86_ops to allow a future patch to do compatibility checks during
CPU hotplug.
Do kvm_ops_update() before compat checks so that static_call() can be
used during compat checks.
