This fixes the following:
target-i386/cpu.o: In function `kvm_cpu_fill_host':
target-i386/cpu.c:783: undefined reference to `kvm_state'
I didn't notice the problem before because GCC was optimizing the entire
kvm_cpu_fill_host() function out (because all calls are conditional on
kvm_enabled()).
* cpu_x86_fill_model_id() is used only if CONFIG_KVM is set, so #ifdef it
entirely to avoid compiler warnings.
* kvm_cpu_fill_host() should be called only if KVM is enabled, so
use #ifdef CONFIG_KVM around the entire function body.
