Fix T81934: Painting/Sculpting in ortho fails to let strokes pass through clipped geometry

Caused by rB7878adf49cff.

When getting the stroke location via raycast in ortho view, the above
commit flipped the condition of the check to perform adjustments on the
rays start/end. This would thus happen (even though it shouldnt),
resulting in wrong depth and stroke location.

Now just flip the condition back, so adjustments only happen when
clipping is OFF.
