    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 
    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.
