    x86/cpufeature: Reposition cpu_has_{lfence_dispatch,nscb}
    
    LFENCE_DISPATCH used to be a synthetic feature, but was given a real CPUID 
bit
    by AMD.  The define wasn't moved when this was changed.
    
    NSCB has always been a real CPUID bit, and was misplaced when introduced in
    the synthetic block alongside LFENCE_DISPATCH.
