    x86/msr: Drop stale comment for vcpu_msrs.spec_ctrl
    
    More than the bottom two bits are now defined, and the MSR policy work has
    shown that using non-architectural representations turns out to be 
problematic
    for more than just asm code.  As the architectural representation is the
    expected default, we don't need to justify why we are using it.
