[PATCH] kvm: compile process_smi_save_seg_64() only for x86_64

[Alexander Kuleshov]

The process_smi_save_seg_64() function called only in the
process_smi_save_state_64() if the CONFIG_X86_64 is set. This
patch adds #ifdef CONFIG_X86_64 around process_smi_save_seg_64()
to prevent following warning message:

arch/x86/kvm/x86.c:5946:13: warning: âprocess_smi_save_seg_64â defined but not used [-Wunused-function]
 static void process_smi_save_seg_64(struct kvm_vcpu *vcpu, char *buf, int n)
             ^
