    libxl: slightly correct JSON generation of CPU policy
    
    The "cpuid_empty" label is also (in principle; maybe only for rubbish
    input) reachable in the "cpuid_only" case. Hence the label needs to live
    ahead of the check of the variable.
    
    Fixes: 5b80cecb747b ("libxl: introduce MSR data in libxl_cpuid_policy")
