Fix broken behavior on active VR Landmark change

There would always be an unintended offset applied. Per design there
should not be any offset when changing VR Landmarks, the view should
just jump exactly to the Landmark.

Due to the recent changes, we don't have to add, but substract the eye
offset we apply to get the wanted behavior.
