Fix T79970 EEVEE: Camera Animation Breaks Motion Blur (Two Steps or More)

This was caused by motion blur camera movement tagging the view as
invalid and thus resetting the temporal sampling.

Critical fix for 2.90. Need second look, but quite confident. This function
is only called once when Motion blur is off.
