KVM: VMX: Fix stale docs for kvm-intel.emulate_invalid_guest_state 



commit 0ff29701ffad9a5d5a24344d8b09f3af7b96ffda upstream.

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.
