[PATCH 3/4] KVM: VMX: Fix stale docs for kvm-intel.emulate_invalid_guest_state

[Sean Christopherson]

Update the documentation for kvm-intel's emulate_invalid_guest_state to
rectify the description of KVM's default behavior, and to document that
the behavior and thus parameter only applies to L1.

Fixes: a27685c33acc ("KVM: VMX: Emulate invalid guest state by default")
