KVM: Use kvm_kvfree() to free memory allocated by kvm_kvzalloc()
The following commit did not care about the error handling path:
commit c1a7b32a14138f908df52d7c53b5ce3415ec6b50
KVM: Avoid wasting pages for small lpage_info arrays
If memory allocation fails, vfree() will be called with the address
returned by kzalloc(). This patch fixes this issue.
