drm/i915/fbc: Use PLANE_HAS_FENCE to determine if the plane is fenced Rather than trusting the cached value of plane_state->vma->fence to imply whether the plane_state itself holds a reference on the framebuffer's fence, use the information provided in the plane_state->flags (PLANE_HAS_FENCE). Note that we still assume that FBC is entirely bounded by the plane_state active life span; it's not clear if that is a safe assumption.
