Sean Christopherson 31e96bc636 KVM: nSVM: Add a comment to document why nNPT uses vmcb01, not vCPU state 
Add a comment in the nested NPT initialization flow to call out that it
intentionally uses vmcb01 instead current vCPU state to get the effective
hCR4 and hEFER for L1's NPT context.

Note, despite nSVM's efforts to handle the case where vCPU state doesn't
reflect L1 state, the MMU may still do the wrong thing due to pulling
state from the vCPU instead of the passed in CR0/CR4/EFER values.  This
will be addressed in future commits.
