KVM: x86: avoid vmalloc(0) in the KVM_SET_CPUID
This causes an ugly dmesg splat. Beautified syzkaller testcase:
#include <unistd.h>
#include <sys/syscall.h>
#include <sys/ioctl.h>
#include <fcntl.h>
#include <linux/kvm.h>
long r[8];
int main()
{
struct kvm_irq_routing ir = { 0 };
r[2] = open("/dev/kvm", O_RDWR);
r[3] = ioctl(r[2], KVM_CREATE_VM, 0);
r[4] = ioctl(r[3], KVM_SET_GSI_ROUTING, &ir);
return 0;
}
