Kim Phillips 5b909d4ae5 x86/cpu, kvm: Add the Null Selector Clears Base feature
The Null Selector Clears Base feature was being open-coded for KVM.
Add it to its newly added native CPUID leaf 0x80000021 EAX proper.

Also drop the bit description comments now it's more self-describing.

  [ bp: Convert test in check_null_seg_clears_base() too. ]
