Ya, apparently I saw something shiny and forgot to get back to this.  In hindsight,
I probably should have spammed v2 right away given how egregious some of these
goofs were, it probably would have been a net positive.  Anyways, this is what I
ended up with for a full changelog:

  KVM: VMX: Move the shared "IRQs off" exit handler(s) to common code
  
  Move vmx_handle_exit_irqoff() and its helpers to common.h / main.c to
  capture that it's a common handler and to allow guarding against incorrectly
  using to_vmx().
  
  Opportunistically use a "vt" prefix instead of "vmx" to communicate that
  it's a shared handler.
  
  No functional change intended.

Yeah, Sashiko pointed out that I was being dense as well.
