Series KVM: VMX: Add helper+macros to do sec exec adjustment | expand

Commit Message

Sean Christopherson Sept. 23, 2020, 4:50 p.m. UTC 
Rename helpers for a few controls to conform to the more prevelant style
of cpu_has_vmx_<feature>().  Consistent names will allow adding macros
to consolidate the boilerplate code for adjusting secondary execution
controls.

No functional change intended.
