[Intel-gfx] [PATCH] drm/i915: Fix frontbuffer false positve.

[Rodrigo Vivi]

Atomic bits needs to be set when cursor check function is returning 0
and intel_crtc is active.

v2: When putting more debug prints I notice the solution was simpler
than I thought. AMS design is solid, just this return was wrong.
Sorry for the noise.
