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.

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