I was supposed to get a topic branch and fix everything up so that both
CPU_BASED_ and VMX_FEATURE_ constants would get the new naming.  When
Boris alerted me of the conflict and I said "thanks I'll sort it out",
he probably interpreted it as me not needing the topic branch anymore.
I then forgot to remind him, and here we are.

The official documentation names are the ones introduced by the KVM pull
request ("Table 24-6. Definitions of Primary Processor-Based
VM-Execution Controls").  In fact consistency with the documentation was
why we changed them.  On the other hand Sean wanted VMX_FEATURE_* to be
consistent with CPU_BASED_*, which made sense when he wrote the patch.

I'll change the names to match for next week's second batch of KVM changes.
