x86, kvm: use proper ASM macros for kvm_vcpu_is_preempted

Browse Source 
The build rightfully complains about:
	arch/x86/kernel/kvm.o: warning: objtool: __raw_callee_save___kvm_vcpu_is_preempted()+0x12: missing int3 after ret

because the ASM_RET call is not being used correctly in kvm_vcpu_is_preempted().

This was hand-fixed-up in the kvm merge commit a4cfff3f0f ("Merge branch
'kvm-older-features' into HEAD") which of course can not be backported to
stable kernels, so just fix this up directly instead.
